I like this - Fun with Math!!! My sister and I are the same way - both math nerds who have fun doing mental math.

I think I have a system figured out. First I add up what each of us ate separately, and determine the difference (usually his is more because I drink water instead of a soft drink). Then I add up the food, tax, and tip, to figure out what the rounded total should be; then subtract the rounded difference I just computed, and divide in half to get what the lesser amount should be. Then re-add the difference to get the greater amount for the other person. Then add both together to make sure the total is correct. Then check to see if F got the same result. I think my system works better than his but I could be wrong!

OK, but do you take it into account if you eat three or four bites of F's. food?

I'm impressed. No way could I do that accurately all in my head. I usually round up in my head and add integers. For example, I'd remember the meal that I order. Say, \$12.50. So in my head the running total is \$13. Then if I order soda to drink, I'd add that as a rounded up integer. But things get tricky as sometimes I'd order a soda without taking a good look at the menu (they aren't the easiest to find). Then again, does the place give free refills? Probably, not not sure. Plus, I have to guess on the tip and tax too. My strategy now is to surrender to a tipping app and do the calculation for what I ate and drank after looking at the check. I trust that more then keeping the totals in my head. Also, like is grade school math, I can always show my work if needed .
