Well, maybe it's just from having a stupid fast typing speed, but since "order of operations" and "BEDMAS/FOIL" only differs by 6 keystrokes (17 letters + 2 spaces for 19 vs 10 letters, 1 slash, and two extended uses of the shift key for 13), it's hard to notice a difference, particularly when I'm not constrained by time issues. I actually had to google bedmas/foil though, as that isn't an acryonym I ever saw used.
