Has anyone been harmed because they learned more math? If someone will be fabricating, they're going to need it. I went to a shop that does stainless sheet metal fab work and drew the guy what was needed, in the way a sheet metal pattern is done and they still screwed it up. After I saw what they made, I almost made a pattern from a piece of cardboard, just so they could trace it, cut it and bend it. All they needed to do is take the dimensions from the other drawing and apply them to my sketch. It was a simple piece, too. Pathetic!
FWIW, the guy next to me in Freshman Algebra was severely disappointed when he got a B on his mid-term report card. If it was a matter of him not understanding the material, it wouldn't have been so bad but he came from Prague when the Soviets invaded and he had done the same work in their equivalent of our 3rd Grade. Of the people I know, who came to the US from another country, I can't think of a single one who isn't more advanced in math AND science.
