It's funny, I just realized the way I do certain simple arithmetic is by actually counting in my head. 8 + 3 is 8... 9, 10, 11. But something like 6 + 5 I just have memorized. Maybe cause my brain has decided it takes too long to go 6...7, 8, 9, 10, 11. Or that I'd forget where I was without using my fingers or something. And now that I think about it, for 8 + 7 I use a third technique: I double 8, and then subtract one. Even though I'm pretty sure I have that one memorized correctly, I still seem to always do that check in my head. Ok, I think it's bedtime. Probably shouldn't admit any of this in a public forum. :)
