How do you know the answer is 81 if you don't know how to get it? I never had a head for math -- my last math course was in 7th grade algebra and it was the only "C" I got in my life. I suspect the hospital of switching babies on me -- my 14 yr old 9th grader is taking pre-calc, getting straight "A"s, and understands how to use one of those bizarre $150 IT calculators. I told her from the get-go, "If you have trouble with your Math homework don't even ask me.". I wonder what it would like to have the math gene...... Julie Krueger heavily reliant on standard calculators that add, subtract, multiply, divide, and figure percentages (and the last one's kinda tricky). And no, I'm not retarded. At least not officially. ========Original Message======== Subj: [lit-ideas] Don't Laugh (Math) Date: 6/23/06 2:36:50 P.M.

I know the answer is "81", I just don't know how to get it. It's starting to frustrate me. I haven't done this stuff in almost ten years, and I can't for the life of me remember how to go about it (although I seem to be getting the hang of some of the other ones...?)
