In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

check it by division.  21/13=1R8 83/13=6R5 50/13=3R11 117/13=9, so 21307/13=1639 and post #1639.
