But I just do that for trig. equations. To do that for simple multiplication or division - as per what you advocate - is just insane.

I want people to be able to figure out what 6*7 is, in case they have forgotten the answer. If somebody is not able to figure out what 6*7 is without using a calculator, then something went seriously wrong in his math education. That's what I'm saying.
