Not bad

Made an error in the first video but definitely nailed the topic

Nice Podcast! Thank you, Kahn Academy 🙂👍🏼!!

Scrupulous, I love Geometry 🙂, these mind boggling teaching are amazing yet a simplistic, dimensional yet logistic, dynamical yet mechanical and fun way to learn the inner and outer dimensions of space, without time and energy applied!

Wrong

In the first video, he claims that 144-36=112 while it actually equals 108.
