I like the way that you go step by step and not take it for granted that we should already know the smallest step.

This video doesn’t explain….WHY DID YOU RANDOMLY DECIDE TO DEVIDE BY 2….why not do b/50a?….just coz it suits you doesnt mean its a proof!

MATH PORN!! I was so frustrated using this formula and not knowing where it comes from! Why don't teachers start by writing the proof first? Now it makes sense for me to use it. Thanks a lot!

Root memorization. Most people can show you what you need to do. Explaining why is what most people cannot tell you.
