Cool Math Trick – Speed Math

I like to think I’m pretty good at doing math in my head but this math teacher’s speed on solving this problem blew me away. He challenges his class to a speed math contest where they can use calculators and he’s just going to use the chalkboard and his mind. He crushes them but is kind enough to explain to the students how he solved the math problem so quickly.
