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
My dad taught this to me when I was 10 and it made my life so much easier. It’s called Vedic Mathematics and there’re a lot more short cuts like this!! Google it (:
