I'm glad you brought that up. I often argue, Why is it rude to correct someone's English and spelling, but not their math? I don't mean we should all go around correcting everyone's every mistake, but why the difference? Yes, you could argue that math mistakes are more likely to affect people negatively, but English can get you, too.

I was average at math in school, just barely. Sadly, I've recently realized, I have forgotten most of the stuff I knew beyond adding, subtracting, multiplying and dividing. I still know a little here and there about fractions and decimals, but I really never use it much, so much of it has gone by the wayside. I bought a For Dummies book set on basic math and Algebra, but being realistic, who knows if I'll ever get around to reading and practicing again. I have so many books to teach me things, and what's frustrating is, I read some of them, but then never get to use that knowledge, and forget, as if I never read the books at all. It's like it's a waste of time, except that I feel reading and learning are good exercise for your brain.
