I did this also because it IS true, it may not be equal but is true, I thought that was going to be the case. I don't know if I would have gotten it even if they expressed you had to make it compute to 555, or equal to 555. Cleaver though, I like it.
Mansherry HimeSama and goes on for like 100 years when it goes off. Why do channels these waste time on their vids and give us 10 specs when we can just pause the video it's so annoying to fast forward the vid!
I was thinking something similar for number one. When he asks the prompt he says, “How much do THEY cost?”. This could easily be mistaken as him referring to both the bat and the ball. Kind of misleading if you pay attention to every word he says.
It would have been more correct of them to say "How can you take 1 away from 29 and get 30?" Then their answer is correct (since you are removing an I from the roman numerals)
29-1= 30 it cant be solved even in roman numerical too , as if we take 29= XXIX and 1=I , no matter we try to cancel I's in both as their is a (-) sign , that will calculate XXIX-I = XXVIII that is 28 , where did it mentioned we can just rule out an digit like that :P sry if i am wrong, please need proof on that .... lovely content though
EyeOf Dragon u r correct it isnt mathematically correct if we can do something like that then they have to say this also includes elements of creativity
Number 3, 23421314 is also right. Between, 1 and 1 is number 3; between 2 and 2 are the numbers 3,4; between 3 and 3 are the numbers 4,2,1 and between the fours there are the numbers 2131
Question 5 can be answered using calculus. From the limits equation 1/x.. 1/2+1/4+1/8, so 1/2^(2) since the denominator is greater than 1 by some rule that I don't remember, the limit of this approaches 1.
I interpreted it wrong too. I didn't realize you needed ALL 7 numbers either. I put things like: 76+24=100 74+26=100 57+43=100 53+47=100 47+53=100 43+57=100 26+74=100 24+76=100 They used only the numbers 1 to 7 (I assumed not repeating), and a single plus sign. haha
One should realize that the reverse of the eight-digit number also works. It took me far longer than 15 seconds to get it, but that was the first thing I noticed.
Many more ways Normal:15+74+6+2+3 Right to left:3+2+6+74+15 Least to Greatest:2+3+6+15+74 Greatest to Least:74+15+6+3+2 TENS PROBLEM: 12+73+5+4+6 Any more answers???
Simple python code to find all solutions to the the arrangement problem: ... from itertools import permutations perlist = [list(arrangement) for arrangement in permutations([1,1,2,2,3,3,4,4])] answ = [] def complete(array): for i in range (0,len(array)): if i + array[i] >= len(array)-1 or array[i]!=array[i+array[i]+1]: if i-array[i] < 1 or array[i]!=array[i-array[i]-1]: return False return True for i in range (0, len(perlist)): if complete(perlist[i]) and perlist[i] not in answ: answ.append(perlist[i]) print(answ)
Just if anyone wants to know the first one can be expressed with A for Bat and B for Ball giving 50=49+2B solve for B and get 1/2 being .5 and since 50=A+B, given B is .5 and A is 50-B you have A=50-(.5)=49.5 so A=49.5, B=.5 A+B=49.5+.5=50. Just for fun
2. It's not an equation because it doesn't have any variables, and the answer given is incorrect. The correct answer is 5+5+5≠550 3. Solving this problem with 8-digit number requires bit of writing 5. The answer given is incorrect. Apart from arrangements of nines, it also uses some additional symbols such as + and /. There is no right solution. 9. There are millions of other ways of doing it. Here is one for the start: 1+1+1+...+1=100 10. 29-1=30 cannot be right under any circumstances. The provided answer redefines substraction in a non-mathematician way.
They just poorly phrased several of these questions. 5 should be "write a mathematical operation using 4 9's such that it equals 100". 9 should have been "Using each number from 1-7 once and only plus signs, how many ways can you get an equation equal to 100. And 10 should have been "How can you take 1 away from 29 to get 30?"
Some of these have multiple correct answers... For example, on the third one, the answer he put was 41312432. Another answer is the reverse of that, which is just 23421314. I don’t know if there’s any more solutions to this riddle though - I hadn’t gone through all of the combinations. Next time, Bright Side, I would thoroughly go through the riddles you choose. That way you don’t have any chance of a slip up. Just a suggestion.
For the question with numbers 1 through 7, there are way more than 2 solutions, unless I'm missing something.For example: 13+24+56+7=100 13+24+57+6=100 14+23+56+7=100 14+23+57+6=100, etc.
29-1 = 30 can be solved by simply applying the command to subtract. Subtract says to change the sign of the subtrahend and proceed as in addition. Therefore "subtract 29 - 1" is the same as "add 29 + 1" which is of course 30. This is the way all computers work and is difficult for many people who were not taught the proper meaning of "subtract" in school
Number 9 is wrong. Since the numbers 6,4,7, and 3 add up to twenty, and the numbers 10,20, and 50 add up to 80. Since 80 and 20 add up to 100, you can arrange them in any way as long as 1,2, an 5 are in the tens place and 3,4,6 and 7 are in the ones place Examples 56+23+17+4 27+6+54+13 I’m pretty sure there are 24 ways to do it using this method, plus the 2 he came up with
I found 84 solutions for problem number 9. 13+24+56+7 31+52+4+6+7 21+63+4+5+7 12+73+4+5+6 In every Example you can swich the units. That makes 24 ways in the first example (4!) and 20(5*4) ways in the other three. If the tens add up to 80 it works out. 2 solutions😂
5+5+5 ≠ 550..just make it not equal.. it is also true now.
J.B I did the same
J.B even the 3rd question I got a different answer that's still correct.. 23421314
That's what I did!
Same
J.B yeah i also did it
BTW -- You can also draw a line through the equal sign, so 5+5+5 ≠ 550. This is also a true statement.
MrWildbill47 yeah me too
MrWildbill47 yeah I thought it!
Exactly what I did!
I did this also because it IS true, it may not be equal but is true, I thought that was going to be the case. I don't know if I would have gotten it even if they expressed you had to make it compute to 555, or equal to 555. Cleaver though, I like it.
MrWildbill47 they said a straight line
Urgh the alarm clock is too loud :/

Why do channels these waste time on their vids and give us 10 specs when we can just pause the video it's so annoying to fast forward the vid!
these questions were vague and didn't provide enough rules and clarity
Anyone else got bothered by the alarm? I had to stop at number 2 :/
Angel Ramirez me
Angel Ramirez it's so loud and annoying
am I invincible against getting annoyed
I'm too lazy to think...
Koen's Travels You're not the only one😊
#relatable.
me to
Koen's Travels me too
Hello
Question 2... my answer is slash the equal sign to make it not equal.
2nd one has another answer too.....
5+5+5= 555 ... We have to draw a straight line so make equals to to not equals to....... AM I RIGHT??
bade gurunadham
I thought the same
Yeah that was da answer I came up with, too
It's 550
What about 5+5+5 [is less than or equal to] 555, I don’t have the symbol
Is there an actual answer for 9 because he says,”a ‘plus’ sign,” but the answer he said used multiple “plus” signs?
Alexandru Marius Toma no...
I was thinking something similar for number one. When he asks the prompt he says, “How much do THEY cost?”. This could easily be mistaken as him referring to both the bat and the ball. Kind of misleading if you pay attention to every word he says.
Thats why i got failed on it
76+24 and 74+26
@Ballistic Yeah he should have said "plus signS "; also, he didn't say the numbers hadda be in chronological order, either
29-1=30 logic was wrong it seems
kishore p yeah because xxix - i would judt be xxviii
CosmicElijah exactly the answer is wrong
kishore p can you draw one line to make this statement true? Look at me I'm so smart bet u can't figure dis 1 out yeah boi
wrong with written Latin numbers, what confuse us; more correctly: if you take one from twenty nine, it becomes thirty
It would have been more correct of them to say "How can you take 1 away from 29 and get 30?" Then their answer is correct (since you are removing an I from the roman numerals)
29-1= 30 it cant be solved even in roman numerical too , as if we take 29= XXIX and 1=I , no matter we try to cancel I's in both as their is a (-) sign , that will calculate XXIX-I = XXVIII that is 28 , where did it mentioned we can just rule out an digit like that :P sry if i am wrong, please need proof on that .... lovely content though
EyeOf Dragon u r correct it isnt mathematically correct if we can do something like that then they have to say this also includes elements of creativity
It should have been phrased along the lines of "How can you take 1 away from 29 to get 30?"
You can do different bases to get the answer
2:10
Or you can put a straight line on the equal sign, which means 5+5+5 doesn't equal 550, which is technically also true.
I hate that alarm you use. Never use it again.
Yeah it was ringing so long
just skipped that part 😌
RIp Stephen Hawkins. 😭😭
Died on Pi day and on Albert Einstein's birthday.
2:04 In the second riddle you can put a slash on the equals sign and make it 5+5+5 doesn’t equal 550
For question number 10:
29 (base 11) - 1 (base 11) = 30 (base 10)
On the second question. Draw a line through the equal sign to indicate the don't equal symbol.
Cool
Number 3, 23421314 is also right. Between, 1 and 1 is number 3; between 2 and 2 are the numbers 3,4; between 3 and 3 are the numbers 4,2,1 and between the fours there are the numbers 2131
But the BASEBALL BAT is 49 DOLLARS and the ball is 1 DOLLARS
Their difference is $48, not $49.
If the ball was $1, as the bat would cost $49 more than the ball the bat would cost $50 and the total would be $51 not $50
it stated the bat costs $49 more than the ball, if the ball was $1 then that would add up to $51 since the bat would have to be $50
Question 5 can be answered using calculus. From the limits equation 1/x.. 1/2+1/4+1/8, so 1/2^(2) since the denominator is greater than 1 by some rule that I don't remember, the limit of this approaches 1.
8:22 5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5+5=100? You never said you cant use the numbers twice
At 2:00 you can draw a line across the equal sign to make it an unequal sign and it will also be true
Second math game actually i though you need to draw straight line over equal sign so it could be like
5+5+5 (is not equal) 550
@BrightSide
The ages of those brothers can also be 3,5,7. Difference is 2 which is also prime...
2:15 and 3:42
I got only this 2 right lol
For the second one, you can also put a straight line on the equal sign to make it a not-equal sign.
In nine, it said /a/ plus sign, not several plus signs
I interpreted it wrong too. I didn't realize you needed ALL 7 numbers either.
I put things like:
76+24=100
74+26=100
57+43=100
53+47=100
47+53=100
43+57=100
26+74=100
24+76=100
They used only the numbers 1 to 7 (I assumed not repeating), and a single plus sign. haha
The visual of the socks in the draw has them in 3 rows so as long as you grab from the same row which should be easy, would only require moving 2. No?
4:42 editing mistake. Top left corner
Armaan Bhullar I noticed that too
8:21 57+43, 54+46, 64+36, 63+37, 73+27 they all equal 100 :)
Why dont you accept
Blue = 0
Red = 0
White = 0
0 + 0 = is the same
000
+000
+000
---------
000
Lol that works xD
But it have different color that means they are different number
One should realize that the reverse of the eight-digit number also works. It took me far longer than 15 seconds to get it, but that was the first thing I noticed.

Simple python code to find all solutions to the the arrangement problem:
...
from itertools import permutations
perlist = [list(arrangement) for arrangement in permutations([1,1,2,2,3,3,4,4])]
answ = []
def complete(array):
for i in range (0,len(array)):
if i + array[i] >= len(array)-1 or array[i]!=array[i+array[i]+1]:
if i-array[i] < 1 or array[i]!=array[i-array[i]-1]:
return False
return True
for i in range (0, len(perlist)):
if complete(perlist[i]) and perlist[i] not in answ:
answ.append(perlist[i])
print(answ)
??? It's clearly said, that the bat costs 49$.. you can't change it afterwards into 49.50$
Lucia Weber ==>I know right? It specifically said $49 greater than the baseball!
Lucia Weber But if the bat costs 49$ and the ball costs 1$, the bat is only 48$ greater than the base ball
Pyry Kielosto ==>But they said the total was $50, with $49 being the cost of one of the items. So the other item had to be $1.
It never said that the cost of the bat was $49... It said the bat cost $49 MORE than the other item...
I think the graphic used is throwing people off.
Well, i figured out that i have a brain of a toddler, thanks.
i know its not right.. because 5+5+5 = 555!
if the the bat costs 49.50 he should've said so
I only got number 6 right...
same
6:47 "Their age" means togheter. Seperatly it should've been "Every boys age is prime at the moment"
8 fidget riddle: i had 23421314
That's right, if a number is a solution for that problem then its mirror is as well. You can prove that those are the only two solutions though.
Found that too
jazz berends you are correct too ....U just reversed the answer
Just if anyone wants to know the first one can be expressed with A for Bat and B for Ball giving 50=49+2B solve for B and get 1/2 being .5 and since 50=A+B, given B is .5 and A is 50-B you have A=50-(.5)=49.5 so A=49.5, B=.5 A+B=49.5+.5=50. Just for fun
6th
Master Gameing123 i think you were first
your not 6th
I subscribed to you
Abby Strobel thx
Sil Game thx
1:55 just draw a line on the plus sign to make it unequal
How is the first one not 49 and 1 that technically fits
Tyler Hatley right..... Made no sense
49 more than 1 is 50 dum dum
Morgan Skinner your right ...im dumb
Difference would be 48
Tyler Hatley but it still adds to 50
A circle with a line through it, spqce, a capital b followed by three zeros and an explanation point, that is what I give this video.
2nd is a line on a equal sign right? Nope I was wrong
julieyangsaelee they're answer was dumb
You could also put a line diagonally over the equal sign so it makes it not equal
I really like your channel really
Are you in Roblox?

Sorry I missed your video I was at baseball

For number 2 you can put a line through the equal sign and make it an unequal sign
First
Hi bright side
Roboticdoge 64 sorry they are being mean i know how it feels
Roboticdoge 64 your not first.
Roboticdoge 64 ya cause I was
Amigo34 so who cares
Roboticdoge 64 you are not first idiot
For 2. you can put a cross through the equal sign to get ≠, which would also make it true
First
Good job
2:04 you can put a line on the = to make it a crossed out = so that it would mean that 5+5+5 doesnt equal 550
Hi
2. It's not an equation because it doesn't have any variables, and the answer given is incorrect. The correct answer is 5+5+5≠550
3. Solving this problem with 8-digit number requires bit of writing
5. The answer given is incorrect. Apart from arrangements of nines, it also uses some additional symbols such as + and /. There is no right solution.
9. There are millions of other ways of doing it. Here is one for the start: 1+1+1+...+1=100

Evan Brunkow That's not an excuse for them
Anyone here like Melanie Martinez??? Besides me?
Michael Romero ya, and she beefing with her ex bff right?
Michael Romero I dont believe it tho instead I really upset with fan/s that burn, etc her stuff like, gurl thass expensive gurlll
I do
That's irrelevant...
It is very hard 😳. I solved only one question which was about pair of socks 😔
Number 2
Another way is a diagonal line on the equal sign
In the second question, you can also draw a line on top of the equals sign which will become not equals and it will be right!😀
Some of these have multiple correct answers...
For example, on the third one, the answer he put was 41312432. Another answer is the reverse of that, which is just 23421314. I don’t know if there’s any more solutions to this riddle though - I hadn’t gone through all of the combinations.
Next time, Bright Side, I would thoroughly go through the riddles you choose. That way you don’t have any chance of a slip up. Just a suggestion.
5+5+5=550 "1 line can make this true" ----> 5+5+5≠550
In question number two, I putted the line in the equal sign so it turns into an unequal sign
With question 8 the brothers can also be 3, 5 and 7 and it will work fine
In riddle number two you can draw a line in the equal symbol to convert it to not equal, and that would give you a true
For the question with numbers 1 through 7, there are way more than 2 solutions, unless I'm missing something.For example: 13+24+56+7=100 13+24+57+6=100
14+23+56+7=100 14+23+57+6=100, etc.
Any question like the second one all you need to do is draw a line over the equal sign, it becomes not equal
On the second problem, you can also draw a diagonal straight line through the equals sign to make it true.
29-1 = 30 can be solved by simply applying the command to subtract. Subtract says to change the sign of the subtrahend and proceed as in addition. Therefore "subtract 29 - 1" is the same as "add 29 + 1" which is of course 30. This is the way all computers work and is difficult for many people who were not taught the proper meaning of "subtract" in school
I can the alarm sound to wake up from sleep
1:26 just draw a diagonal line through the equals sign
For number 2 you could also draw a line in the equal sign to make it (5+5+5 is not equal to 550)
29-1=30 is correct in undecimal system (base-11) on the left and decimal on the right.
#2 has a second solution:
MAKE AN "NOT EQUAL" SIGN! AMAZING!
'mutters from viewers'
"so simplistic!" "so OBVOIOUS!"
8:24 Another way to get 100 using 1 to 7 digits and a plus sign: Here it is: 17+35+46+2 = 100
29-1=30 can be possible if there was a -29
For example -29-1=30
for number 2, you could also have drawn a line on the equal sign for not equal
Number 9 is wrong. Since the numbers 6,4,7, and 3 add up to twenty, and the numbers 10,20, and 50 add up to 80. Since 80 and 20 add up to 100, you can arrange them in any way as long as 1,2, an 5 are in the tens place and 3,4,6 and 7 are in the ones place
Examples
56+23+17+4
27+6+54+13
I’m pretty sure there are 24 ways to do it using this method, plus the 2 he came up with
All are extremely tough except for the one (pair of socks)
#2 you can put a straight line diagnolly across the equals sign making it NOT equal.
3:10
I had the number in reverse, so instead of 41312432 I had 23421314... Still counts though!
Me too
1:33 Draw a line through the = sign.
1:32 there is another possibility too. Just draw a line threw the equal sign making the equation true. (Line threw equal sign means not equal)
For the second one, u can also put a line through the equals sign making it not true
Today in my 6th grade math class I learned that 2+2=1
#8 could also be 2,3,5 (the differences would 1,2,3) or 1,2,3 (the differences would be 1,1,1)
For every riddle similar to second one, you could also draw a line through the equals sign~
2nd question, you can use the straight line on the equal sign (=) which will make the equation true. 5+5+5 (is not equal) to 550
I found 84 solutions for problem number 9.
13+24+56+7
31+52+4+6+7
21+63+4+5+7
12+73+4+5+6
In every Example you can swich the units. That makes 24 ways in the first example (4!) and 20(5*4) ways in the other three.
If the tens add up to 80 it works out.
2 solutions😂
At question 2 I just turned the equal sign in doesn't equal sign
3:30 just turn on the light and you don't have to remove any socks!
Answer of 9th question can be 54+16+27+3=100(70+27+3=97+3=100)
On number to you can just put a line across the equal sign.
For the brothers one, One is 1, another 2, and the last 3. 3-1=2 3-2=1
