Riddle #4 actually has three solutions. If you move the match going vertical from the plus sign and move it to the 6 to change it into an 8, then the problem will read as such: 8-4=4.
In fact there are four solutions. You can also move the vertical match from the plus sign and place it diagonally over the "equal" sign, so changing into a "not equal" sign. The resulting equation is 6-4 ≠ 4 ;-)
@mashup Math Please let us know, if we can collaborate, as we are working on same genre. It would be good that we can work out together so that we can serve the audiences in a better way.
for question 4 there is another solution as well which is 8-4=4 so you move a matchstick from the plus to make it a minus and put that on the gap of the 6 to make it 8
On question number 4 there are 3 answers: you can move the match stick on the plus symbol to make 8= 8-4=4. We are enjoying video but please be more accurate next time
In addition to Nick Zoa disagreement on #6. When thinking on riddles wording is very specific. There was only the mention of the soda being weighed. I saw an animation of bottled soda so I naturally assumed the bottles weighed something too so therefore the soda weighs more. Right? Wrong I guess! Lol might be deconstructing too much but it was a riddle after all.
3:20 I did solution 1 and another solution which is moving the plus sign stick and making it a minus sign then putting the stick at the equation sign making it like this =/= which means doesn’t equal
One other puzzle used "FIBONACCI'S NUMBER" and I had to look that definition up ! I don't remember "PASCAL'S TRIANGLE" from my old high school days ! I vaguely remember that from my old high school days !
Question #6 has an incorrect answer. Gold is measured in the TROY measurement system in which there are 12 ounces in a pound. Therefore, 16 ounces of soda weigh more than a pound of gold.
If you are going to assume that the gold is in TROY ounces, then you must assume the soda would be in FLUID ounces. And since we don't know which cola it is, the density may be such that 16 FLUID ounces of it could weigh 12 TROY ounces.
You've made a good point and you're partly right. Fluid ounces are used to measure volume, not weight. Although 16 fluid ounces of water weighs 16 ounces, it's possible for 16 fluid ounces of a different liquid to weigh less. For example, 16 fluid ounces of pure alcohol (ethanol) weighs 12.6 ounces. 16 fluid ounces of some grades of gasoline weigh about 12 ounces. However, we're talking about soda here, which is mostly water. So, 16 *fluid* ounces of soda would weigh more than 12 *Troy* ounces of gold.
On # 4 we found a new solution You could the match stick from the plus and move it to the sixth and it would make it eight so it would make it 8-4 = 4 👏🏻👏🏻👏🏻👏🏻 just so you know
Can you help me with this one: You've managed to break into the vault of a bank filled with 20 sacks of coins. One of the sacks contains gold coins, while the other 19 are filled with counterfeit gold coins. You cannot tell the difference between the gold coins and the fakes by handling the coins, looking at them, biting them, or testing them. The fake coins weigh exactly 1 ounce each, while the real gold coins weigh 1.01 ounces. There is a large scale with enough room for all the sacks in the vault, but as soon as you weigh something it will trigger an alarm, so you can use the scale just once before you must flee the vault. How can you figure out which sack of coins contains the real gold by only weighing something on the scale once? Note: The scale tells you the exact weight of whatever you put on it, it is not a balance scale. Hint: You might want to consider labelling the sacks. And remember, you can take coins out of the sacks and weigh a combination of them.

In the number 4 there's another solution which is you get the matchstick from the plus sign and make it minus then put that matchstick in the six it will make 8-4=4
All were very easy, mathmetician or no. I missed 9 because I was always bad at ELA and didn't stop to think what it meant. 10 (I got right but) is false because how would the top hex be worth 1?
2:59 To those who say there is a third solution, the vertical stick in the plus sign is under the horizontal stick. So moving it inevitably moves two sticks. *insert genius black guy meme*
And you are correct because they may be twins but the younger one was abducted at birth to a planet with a revolution time twice Earth's so she would only have half the number of years.
I was here because my math teacher sent me the link in Microsoft Teams becuz of Coronavirus which kids need to stay home (I am a kid as well) #StopTheCoronaVirus #StaySafe #WashYourHands
#7 is weird, in the equation it says "the hoodies costs $100 than the pair of shoes" but the equation is not saying that the hoodies is more than $100 it is saying it is $100 more than the pair of shoes. It is worded very weird correct me if I'm wrong.😀
Where a is the cost of the hoodie and b = the cost of the shoes: a+b=150 a=b+100. Substituting b+100 for a in the first equations results in b+100+b=150 or 2b+100=150. Subtracting 100 from both sides results in 2b=50 and dividing both sides by 2 results in b=25. Now, back to the first equation replacing the b with 25 results in a+25=150 and now we subtract 25 from both side and the results is a = 125. But the BIG QUESTION is who would pay 125 DOLLARS for a hoodie?

In R4 I DRWA STICK WHICH IS HORIZONTAL AND PLACED ON 6 HEAD AND MADE HIM 8 SO NIW EQ IS 8 -4=4
Hello
in math riddle 4 there is another solution :
remove the matchstick of plus and it will be:8-4=4
I was thinking the same thing!!!
ya I did it in school it has three solutions and your right
Yes I got that too
that was my only answer
@@sammymeyers8573 me too
3:18 Solution 3: move the vertical line from the plus and put it at the 6, so it will be 8-4=4.
solution 4: move the vertical line from te plut and lay it diagonally over the = sign
I did the same thing
@@hajowennekes9799 True, but not valid lol
@@JosiahFickinger his solution is ABSOLUTELY valid...
6-4 DOES NOT EQUAL 4
The diagonal line over the equal sign is Not Equal.
@@LaxerFL I know. But that'd be true for almost anything. I feel like it kind of defeats the problem 😉
3:18 Solution 3: move the matchstick of plus and place it over the equal symbol...
So 6 - 4 ≠ 4 🌝
@Phoenix23x11_rl after 1 year.. 🌝
Riddle #4 : 8-4=4
Kiko Sotto ya I thought of that
That was my first thought
Same here
Yes I thought of it for my first answer then I did 5+4=9 like that was my first answer so am I smarter than the person who made it🤔😺
same i am thinking the same thing

Bro that was what i was about to say
CLEVER !@@stevepeacock7670
I love these and refer to these as "Get Your Math Brain ON!" Thank you for these resources!
Mrs. Mitchell's 5th Grade Class thinks the numbers are 1, 5, 10, 10,5, 1. Thanks for sharing your video!
I also think that!
You are right! I thinked about that too!! 😂
Ok
She’s right
3:17 there is another answer you can remove a verticle matchstick from + and move it to 6's upright gap
I.e,8-4=4
@mashup Math Please let us know, if we can collaborate, as we are working on same genre. It would be good that we can work out together so that we can serve the audiences in a better way.
for question 4 there is another solution as well which is 8-4=4 so you move a matchstick from the plus to make it a minus and put that on the gap of the 6 to make it 8
thanks yo
ya I was confused as well because I did that in school and there were three solutions
I was going to say that but yeah wow
On question number 4 there are 3 answers: you can move the match stick on the plus symbol to make 8= 8-4=4. We are enjoying video but please be more accurate next time
I also found that solution
Yes
😱 you are brilliant really
Please make more videos like this
bonus question apple and strawberry IS 1，coconut and peach is 5，pear and watermelon is 10
Kindly upload more videos. Thank you.
Answer to bonus question: (numbers from left to right) 1, 5, 10, 10, 5, 1
2:59 you can also do 8-4=4
Move the vertical +match stick with the 6
11/10. Yay.
nice riddles
Mrs. Frith's class thinks it 1,5,10,10,5,1 We love your riddles. Thank you.
Riddle 10: the sum of every row equals times 2 of the sum of the row above it row 3 is 4 and row 4 is 8
161051 is the answer of the bonus question 👍👍👍👍
I got everything except what to put between 7 and 8 so easy man.
3:12 6-4≠4
These really aren't that hard, I got 8/10 for the normal ones.
Bonus:
Strawberry = 1
Coconut = 1+4 = 5
Pear = 4+6 = 10
Watermelon = 4+6 = 10
Peach = 1+4 = 5
Apple = 1

Also you could move the vertical line from the plus to the equal sign so it would be 6 - 4 ≠ 4.
Question 2 really stumped me
3:20 I did solution 1 and another solution which is moving the plus sign stick and making it a minus sign then putting the stick at the equation sign making it like this =/= which means doesn’t equal
#5 can also be 7.5 because it would be become a logical rythm 6.5
One other puzzle used "FIBONACCI'S NUMBER" and I had to look that definition up !
I don't remember "PASCAL'S TRIANGLE" from my old high school days !
I vaguely remember that from my old high school days !
1,5,10,10,5,1
Also, I got all correct, you should have posted harder sums
Is the riddles same with non routine problems?
Seriously got all except one
Question #6 has an incorrect answer. Gold is measured in the TROY measurement system in which there are 12 ounces in a pound. Therefore, 16 ounces of soda weigh more than a pound of gold.
Yes
Please look at the balance again. 3 soda for 3 gold makes the scale balanced.
If you are going to assume that the gold is in TROY ounces, then you must assume the soda would be in FLUID ounces. And since we don't know which cola it is, the density may be such that 16 FLUID ounces of it could weigh 12 TROY ounces.
You've made a good point and you're partly right. Fluid ounces are used to measure volume, not weight.

Answer to BONUS ques: 1, 5, 10, 10, 5, 1
The answer to the bonus question is 1,5,10,10,5 and 1
On # 4 we found a new solution
You could the match stick from the plus and move it to the sixth and it would make it eight so it would make it 8-4 = 4 👏🏻👏🏻👏🏻👏🏻 just so you know
Bonus answer is 6,3,5,12,6,8
8:22 the Strawberry and apple are covering 1, the coconut and orange cover 5 the pear and the water melon cover 10
for question 4 I found another answer 8-4=4 you move the matches form the plus symbol and move it to the six.
🍓=1 🥥=5 🍐=10 🍉=10 🍑=5 🍎=1 I solved the bonus riddle!
2:12 what about 1, -1, 0
I only missed #9 because I don't have no knowledge of US coins. But I guessed it would be 25+5 or 20+10.
3:16
there is another solution also if u move one of the sticks from the plus sign and add it to the six the equation will be 8-4=4
U KILLED MY BRAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I like it
#7 let hoodie y and shoes x
x+y=150
x=150-y equation 1
Now ATQ
x+100=y
From equation 1 150-y+100=y
2y=250
y=125
x=150-125=25
There is a third solution. It is taking away one of the lines from the plus and make the six eight and then it would work

I like it is very interesting.
3:31 8-4 = 4 - there are 3 solutions for riddle 4
who got thisfor online school
Me
Not me
in ridlle number 4 this can also possible that moving 1 stick from + to the blank space of 6 will make this equation = 8-4=4
there is a 3rd solution in riddle 4 : 8-4=4, try it out
3:00 8-4=4 also will be the solution

Gold is measured in troy weight, which is 12 ounces per pound. 16 ounces of soda weighs more than a pound of gold.
I solved the first 2 with ease correctly
at riddle #4 u could do 8-4=4
1,5, and 10
In the number 4 there's another solution which is you get the matchstick from the plus sign and make it minus then put that matchstick in the six it will make 8-4=4
For me #1 was shoking. There are 14 squares in 9 squares. WOW!!!!
By the way i got another solution on number 4 which was 8 - 4 =4 i moved the matchstick in the plus sign
OMG tomorrow's scimatics event and i wish this riddle comess!!!!!!!!!!!!!!!!!!
#4 actually has a 3rd one. 8-4=4
8/10🎉
These are so easy.
8:21
The answer is 161,051
Just multiply the numbers by 11
I got 4 out 10. How did I do?
Hello! We found another solution to #4 at The Beachmont School in Revere. You can move a matchstick from the + sign to make it 8 - 4 = 4 :)
for the fourth question u mist a solution. u can move the vertical matchstick of the + and move it to the six
Decimal point q5
Hello
in math riddle 4 there is another solution :
move the matchstick of plus and place it over the equal symbol...
So 6 - 4 ≠ 4 🌝
8-4=4
0-4=4
5+4=9
Bonus (from left to right)
1, 5, 10, 10, 5, 1
pascal triangle, so 1 5 10 10 5 1=32
I think the numbers covered up are 1,5,10,10,5 and 1
Bonus 1,5, 10, 10, 5, 1
For riddle 4 there is a third solution: change + to - and 6 to 8
All were very easy, mathmetician or no. I missed 9 because I was always bad at ELA and didn't stop to think what it meant. 10 (I got right but) is false because how would the top hex be worth 1?
Solution 3 for 4 question is 8-4=4
on number 4, you could have made it 8-4=4.
Strawberry and apple are both 1 coconut and orange are 5 pear and watermelons are 10.
2:59 To those who say there is a third solution, the vertical stick in the plus sign is under the horizontal stick. So moving it inevitably moves two sticks. *insert genius black guy meme*
But you don’t know that? And it’s technically only moving one because only one switches its place.
Strawberrry is 1 Apple is 1 Coconut is 5 Peach is 5 Pear is 10 Watermelon is 10
1:30 There is not enough information given, so there are two answers. 37 or 20
And you are correct because they may be twins but the younger one was abducted at birth to a planet with a revolution time twice Earth's so she would only have half the number of years.
Question 4 has another solution. you can move the match stick to make it 8 - 4 = 4
This will not confuse math and physics (science) nerds. For me it was normal and Riddle 4 it can be 8 - 4 = 4 also.
Riddle #4: third solution: 8 - 4 = 4
what is the level of the questions?
3:18
8-4=4 as well 😁
I was here because my math teacher sent me the link in Microsoft Teams becuz of Coronavirus which kids need to stay home (I am a kid as well) #StopTheCoronaVirus #StaySafe #WashYourHands
I'm also a kid. I found this before my teacher in virtual classes.
#7 is weird, in the equation it says "the hoodies costs $100 than the pair of shoes" but the equation is not saying that the hoodies is more than $100 it is saying it is $100 more than the pair of shoes. It is worded very weird correct me if I'm wrong.😀
Where a is the cost of the hoodie and b = the cost of the shoes: a+b=150 a=b+100. Substituting b+100 for a in the first equations results in b+100+b=150 or 2b+100=150. Subtracting 100 from both sides results in 2b=50 and dividing both sides by 2 results in b=25. Now, back to the first equation replacing the b with 25 results in a+25=150 and now we subtract 25 from both side and the results is a = 125. But the BIG QUESTION is who would pay 125 DOLLARS for a hoodie?
I got 9/10 and got the bonus right (so 10/11)
