Ok but this is actual a very useful way of thinking about algebra problems. Much easier to add large numbers in your head or solve simple equations if you get practiced at this

I've always done it this way and don't have adhd

My retarded ass: 9 is 0b1001 and 7 is 0b111, 0b1001+0b111 is 0b10000 which is 16.

Am kidding, I take 9's ten friend, sub-stract that from 7 et voilà I have 6 ones and 1 ten which is 16.

Holy shit.

Is that not how “normal” people do math in their head? How do they do it?

This is psychopathy. Clearly you just add the 1 to the 9 to make it 10 and subtract it from the 7 to get 6 and 10+6 = 16.

10 + 7 = 17 17- 1 = 16

Your teachers are bad at their job. There is nothing wrong with that method. Now, if you also try to do 7+3 as 5+5, you might need to learn other method so next time, you choose a more efficient one. But against that would not be wrong.

9 is one less than 10, and 7 is three less than 10, so combined, they're four less than 20 = 16

Is this engagement bait to get all the people who do it differently because it worked lol

That’s the most logical way! They are the heathens!

I used to work at a gas station, and I was always giving different amounts of change, and so I accidentally memorized every single possible combination of digits and coins from 1 to 99.

I no longer have to think, I have a lookup table.

The legend said that it is how Gaussian elimination was discovered in europe

lol yep, precisely

As long as your method gives you the correct answer, I see no need to correct anyone.
