396+697=1,093 Round 396 to 400 (-4), then round 697 to 700 (-3). Add the newly rounded numbers (400+700=1,100) and combine the differences ((-4)-3=(-7)). Subtract (1,100-7=1,093).
0:53 Trick 1 quick division by 5 (I learned it by myself lol) 2:17 Trick 2 add large numbers using rounding (cool trick I like it) 4:07 Trick 3 the percentage trick (also from another youtuber) 5:15 Trick 4 tables of 7,8 and 9 7:41 Trick 5 multiplying any 2 digit numbers up to 100 (the method is just like the japanese method)
u should also teach why u can do those "tricks", for example in the first trick dividing by 5 is the same as multiplying by 2/10 wich is what we are doing, or showing that for example 16% of 75 is equal to 75 X 16/100 and by the rules of multiplication its the same as doing 75/100 X 16 etc, I think most people understand where this tricks came from without needing someone to explicitly show them but still it would be better for people who may not be so good at math
Here is something that is an interesting. Multiply any two digit number by two to twelve. The rule is you can only multiply by 2, divide by 2, add subtract plus add a zero to the end of the two digit. To multiply 57 by 7. 1 add 0 to the end of 57 - 570 2 divide by 2 - 285 3 multiple 57 by 2 - 114 4 add 285 to 114 - gives 399. You don’t need to stop at twelve but start with 12 then progress once your confidence grows!
Wow! This is great stuff! What my auntie always told me is, '' Maths is a type of language that you should always understand. Never give up, but read the question until you understand, just like discovering a new language." ❤❤ P.S. WE SHOULD 100% HAVE PART 3
*The trick of rounding.* I acquired this power at 6 to 7 years old when I am learning addition, subtraction etc. Make more cool tricks which I and most of your audience dont know!
You should also teach table 4 is 2times of table 2, like wise tab 6,8,10,12,14,16,18,20,22,24,26,28,30,32, and all even numbers tables are 2 times of 3,4,5,6,7,8,9,10,11,12,13,14,15,16 etc tables.
Trick 1 : Knew it but thanks for another perspective (mine was multiplying 2/2 on both N and D) Trick 2: standard method is faster for me, idthink i'd use this Trick 3: Saw it on a meme Trick 4: who the heck can't remember tables of 7,8,9 😭 Trick 5: Standard method is still fast for me (I've practise) Thanks for the video none the less

Ok
We need part 3 !!
i truly found it amazing you know i was having anxiety now my anxiety is gone and i like it and even learned cause i am going to grade 9this year
People need calculators for 12minus 8 these days! Seen it multiple timescale I am absolute I’m not the only one
396+697=1,093
Round 396 to 400 (-4), then round 697 to 700 (-3).
Add the newly rounded numbers (400+700=1,100) and combine the differences ((-4)-3=(-7)).
Subtract (1,100-7=1,093).
Wow This is crazy math! Remember to never give up. You should do a part 3!

2:17 Trick 2 add large numbers using rounding (cool trick I like it)

7:41 Trick 5 multiplying any 2 digit numbers up to 100 (the method is just like the japanese method)
The quick division trick is wrong. I really don't know why when dividing a number like the method in the video is wrong
@@AmnahAhmed-z3l It's not wrong.
x/5 = x * (1/5)
1/5 = 2/10 (1/5)*(2/2)
x/5 = x * (2/10) = (x * 2)/10
u should also teach why u can do those "tricks", for example in the first trick dividing by 5 is the same as multiplying by 2/10 wich is what we are doing, or showing that for example 16% of 75 is equal to 75 X 16/100 and by the rules of multiplication its the same as doing 75/100 X 16 etc, I think most people understand where this tricks came from without needing someone to explicitly show them but still it would be better for people who may not be so good at math
Noted. Thanks for the feedback :)
HeLP

1 add 0 to the end of 57 - 570

3 multiple 57 by 2 - 114
4 add 285 to 114 - gives 399.
You don’t need to stop at twelve but start with 12 then progress once your confidence grows!
3:23 An easier way is to just add 700 and 200 and then add 68 and 7.
We need part 3
This is sooo sooo amazing! Much better than part 1. Thanks ❤
Multiply by 5 - write the number with 0 (to make it even number)and devide by 2 will give you answer.
E.g 193 write as your answer 1930/2=965
Q1:
9723/5 is 1944.6
Q2:
396+697 is 1093
Q3:
Coming soon!
Q4:
Works
Q5:
46×68 is 3128
Greatest mathematics video! 🎉🎉🎉

Multiplying by 5:
Divide the number by 2
Multiply it by 10
Bro make an video on division tricks also
3128 is the answer to that last question, thanks for the trick
Keep practicing
Trick 1 : Knew it but thanks for another perspective (mine was multiplying 2/2 on both N and D)
Trick 2: standard method is faster for me, idthink i'd use this
Trick 3: Saw it on a meme
Trick 4: who the heck can't remember tables of 7,8,9 😭
Trick 5: Standard method is still fast for me (I've practise)
Thanks for the video none the less
Appreciate you taking the time to watch and share your thoughts 🙌
We need part 3!!!
yeees
exactly
Thanks bruh 👊
Can you make a vid on intedration.
Already made

Waaaw ❤ the best please continue
I already discovered the trick of dividing by 5 by myself when I was 6 or 7 years old. *LOL! 😂😂😂*
3:54 : Its 1093
2:08 1944,6
You are great
Please give me the link of part -3
Part 3
9723 / 5 is 1944.6
part 3 !!!!!
9723/5=1,944.6
396+607=1,003
148% of 25=37
46x68=3,128
697
No 1 Answer: 1944.6
Part three
2:08 : Its 1944.6

love it
4:00
1 093
thanks
PART 2 PART 2
2:09
1 944,6
3:34 why - ? You're rounding up not down
rounded down as well (later when using 207 as 200)
9723 : 5 = ?
=9723 x 2
=19446
=1944.6
9723 : 5 =1944.6
How the heck did the 7 become 15 by adding 1 to it
it is so amazing🤩🤩🤩😍🥰🥰
Cool video!
But you didn't explain how to do 46x68 in 5 seconds did you? Maybe do 50*68 then subtract 68 4 times might be doable in your head.
For some reason I get kind of mad when I hear "99% of people" cuz it's like those brainrot shorts

You can’t escape your fate I will find out how will leak the anwser
We know that we are done when we have to calculate 53% of 63. 😂
I have also done in 0.05 years 😂

148% of 25= 37
Easy........😂😂😂😂
7..(3×8)=24...then.(8_3)=5
