HOW DID I NOT KNOW THIS?!

Why do I learn more about math from Tumblr than my 12+ years of formal education????????

No math teacher ever taught me this trick. Got damn.

This is great and all if you know how to subtract things from 100 

lmfao at the gif!

I think I did it wrong. I am terrible at math

‘Kay, sure. Let’s try it with 47 x 68 now!

 47        x      68        =
100-47       100-68
   v               v
 53      +      32 > 85

          x

uhhh…. shit. Now I have to multiply 53 and 32 for the second part! Guess I’ll have to do it again…

 53        x      32        =
100-53       100-32
   v               v
 47      +      68 > 115 (what do i do with this number um)

Oh. Well. Crap.

There’s a reason no math teacher taught you this trick, kids.
