Learn Ruby the Hard Way – Exercise 27 Memorizing Logic

In Exercise 27, Zed. Shaw wants you to memorize truth tables.

I feel like I have a pretty good grasp of truth tables (ok, so I only did that ONE logic class in university many years ago… but I really enjoyed it, ok?). I do find I need an extra second or two when it comes to the NOT AND and NOT OR tables. However, feeling confident that I can draw up the tables and get the computed values… I’m going to make the call to skip memorizing. Onward to the next exercise!
