Thank you , I was having a headache today, so I left school, and when I was gone, my teacher taught me this

Why do it the easy way when yau can do it the longer way

Old school way is the new school way

Old school, for sure.

What if the dog is Cerberus and it can fly? 😂✌️

You did it wrong the least common denominator is 18

😊 Ni

Need for number bro

Cheer~~~~agreement or harmony-- compatibility.😊

Thx, i needed this

Me who's singaporean and does it the american way u shown:😐

Nice explanation budd

ur voice is so hot

The Swiss: Start at the left write the sum from left to right. It will be 6 4, add 1 to the bottom 3, difference will now be 3 instead of 4, then 5 will be left.. You will get 53.46.

Superb video sir . I am very clear ❤

Doubt it works as well with longer numbers requiring multiple carries.

America

It would depend on the numbers. .80 is a nice round number so the latter works better but sometimes the first method would be faster. I usually do the latter when doing calculations in my head but the first method when the problem is written.

awesome

WHAT

America

I actually use both methods. Plus the count up method. Never heard them being called „American“ or „Singapore“.

Yeah nice make a new problem to solve a problem

So does this method work on all math subtraction problems?

Bro just do it my way 23 -15 + 5 = 20 +3 = 23 --- 8 (because you add 5 and 3) Every time I go through any math equation that’s what went through my head for anything simple like that. lol Maybe that’s why I’m bad at math

Yup, works with big numbers

I just added 8 to 15 and got 23 so I know the answer is 8

Or use your mind like I was taught in 1st grade.

Seems like this might be useful in more complicated problems. Obviously you used a simple problem for illustrative purposes.

Extra step

This is the 'stupidest' math hack, and you should be ashamed you presented it. We all lost IQ points watching this...

This is what I've always done. I have no clue what you did in the beginning

Took to long❤

Nice

Or, You could run around the block and get a pizza and tie your shoe laces together and read a book backward after getting a mohawk haircut then do the subtraction problem like an educated person.

Sounds to me like subtraction with extra steps.

😂😂😂 I will stick to the original method 😂

bro discovered algebra

The truth value of a conditional statement is not dependent on the truth values of its constituents, only how they relate to one another. 6 times out of 7, it is not Monday, but regardless of weather "today is Monday" is true, it follows that when it is Monday, it will be Tuesday. On Saturdays, the statement "tomorrow is Sunday" is true, but it as a conclusion does not follow from the condition "today is Monday", so the overall statement is false. In the third statement, there is no causal connection between dogs having 3 heads, and dogs flying; the conclusion does not follow from the premise, therefore it is false. It's just as easy to imagine a hypothetical where dogs have 3 heads and fly as one where dogs have 3 heads and don't. In the fourth statement, the conclusion is something that is true in all conditions, regardless of their truth values, and thus it is overall true. Even if hypothetically, sharks walked on land, 1+1 would still be 2.

Thank you this is rly gonna help me for my exam tmrow

Thanku

Thanks

This is a superb explanation. It made the topic easier to understand.

??????????????????

this was so simple to understand thank you

thanks so much

What? you litterally explained it better than my Math teacher. RESPECT

Thank you, you explained this very well. You made me understand.

Thanks bro

Bro thanks
