This is a good read on how to commit concepts to long-term memory and building skills.

I think there is a typo in the article though; there is a point that says:

> work out the problem by computing 6 × 5 = 5 + 5 + 5 + 5 + 5 + 5 = 30 (or 6 + 6 + 6 + 6 + 6 = 21)

The second parenthetical statement should be 30, unless I’m missing something?

Whoops, yeah, that's a typo. I think I originally had 7x3 as the example. Thanks for catching it.
