having to use a calculator is pretty sad. should be easy if you learned your multiplication tables in 3rd grade.

You'd be surprised how bad most people are at math. I'm teaching HS math now and half my students don't know that 1 1/2 = 3/2, 1/2 = 0.5, etc. I'm talking about 16-17 year olds here. I think the reason it's like this is that people are given calculators to solve problems before they actually understand the fundamentals.
