[–] bitwizeshift 1y ago ↗ 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? [–] JustinSkycak 1y ago ↗ Whoops, yeah, that's a typo. I think I originally had 7x3 as the example. Thanks for catching it.
