what is the last productive thing you've done to go to the anime world? me? i learned some math. i learned that for example, you want to calculate what 152 + 427 is you calculate it this way, you add 1+4 for first digit, it's 5 btw, you add 5+2 for second digit, it's 7 btw, and you add 7+2 for the third digit, it's 9 btw, therefore the answer is 579. honestly it was a great discovery for me, it sped up my mental math, before this i would be like whats 4+9? i would count like from 4 9 times like 5 6 7 8 9 10 11 12 13. yeah answer is 13.
just type it into a calculator
Very proud of of you anon, hopefully you tackle subtraction next.
>>282301038Science.
>>282301038I see. Here is another trick. If you want to calculate say 7% of something. You can just calculate 10% and 1% which are easy, and then subtract 3 times the second from the first.
