I am not talking about quantitative reasoning, however, I am more concerned about GenChem math. Does anyone know any good resource (other than Chad's) that provides one with tips and tricks for solving math with decimals? I seem to have a hard time determining the square root of a number like 0.1975 in my head, for example. I know that its approx 0.45 since 4x4 = 16 and 5x5 = 25 so its half way between 4 and 5, but some other problems are tricky.
