Have you ever been that person? Flowcharting: a lost art. It doesn't have to be complicated, but ti shouldn't be too "clever", either. Mostly, it should be readable so people in your audience can understand it (not everyone involved in a project is an expert coder). Readability, and easy understanding, are why I

The other point we'll call Point B, was at (2, 4) -- so it wasn't a rotational image of Point A. Point B has up and moved itself, which points don't

mister-wunderkammer:
Counting in binary
Instead of counting up to five on each hand, a binary system can be used to count up to 31 on one hand, and up to 1023 on two hands. This is done by using your fingers to represent increasing numbers, multiplying by two each time.
Once the numbers 1, 2, 4, 8 and 16 are assigned to the fingers, as above, different numbers can be represented by raising or tucking in the fingers. A raised finger represents its number being “on”, whereas a lowered
