Teacher was hiding this from you🤯

Was I the only one taught “flip, change, keep”?

That’s basically how I learned

Yes this is called butterfly method

Wait so they don’t simplify the fractions anymore?

Yes we should simplify

Cool tricks, zero conceptual understanding

Nobody is hiding anything freak this is basic… division is the reciprocal of multiplication

Yes but some people don’t know

in the first one's final answer both parts should also be divided by 2, we were taught to make the division until it's no longer possible, ideally

Yes I know

my math teacher taught the division and multiplication exactly that way. not the adding and subtracting tho..

You can add and subtract any fraction like this

No, every math teacher on the planet taught that.

Ok 👍

Teacher didn't know ‼️🤣‼️

Maybe😄

But this is literally how these things are taught

"12/14" bro was holdng back from saying 6/7

For addition/subtraction, this doesn’t work. Take below examples. (5/12) + (1/16) (2/12) - (1/16)

Who said it doesn’t work

Nein. "Brüche werden dividiert, indem man sie mit dem Reziprok multipliziert."

This is exactly our teacher taught us ❤

Thank you for appreciation

🤣🤣 wild

😅

Simplifying also needs to be included. 😊

Yes next time will do

First ones wrong

I missed out on this teaching due to being sick for the week of school and could never understand this whatsoever and am figuring this out 15 years later

Ok now you have finally understood this😄

This is exactly what it’s taught…

Yes

Where did you go to school? I still remember being taught that in elementary school.

That’s literally how I learned to do each of those things back in the 3rd grade, which was 1975 for me.

Ok

No one hide, this is how we clear our school exams

Ok

A quicker way to do the adding and subtracting

Yes

no trick for simple question. all those tricks are derived from base definitions

I don't understand addition and subtraction

Watch again you’ll understand

Good luck

Чушь, именно этому в школе и учат. Только учат включать мозг - переворачивать дробь и приводить к общему знаменателю, а не делать это чисто механически по алгоритму, не понимая процесс.

You forgot to simplify the answer

Simplify

No, just very basic knowledge

that's like toddler math problems, you created whole company to generate such bs?

At least, my teachers didn’t

Ja klar, in der Baumschule! Was für ein Blödsinn, das lernt jeder in der Schule, man muss nur hingehen.

I would have gotten 50% for my amswers because 2 of them are not simplified
