I think I'm a mixture of what most people have posted so far... for single digit numbers, the answer just "pops" in because I've memorized it. For larger numbers, I apply certain memorized rules if I can (like "any number multiplied by 1 is itself", or "any number multiplied by 10 just gets a 0 added to the end of it", etc.) or I break it down into pieces, usually at a common "5" or "10" point. For example, to do 45 * 32 in my head, I'll end up doing (45*30) + (45*2). To add 857 and 249, I'll end up doing (850+250) + (7-1).
