Review: Perfect! - Got this for my daughter who needed it in college for chemistry classes. She said it works great! Would recommend.
Review: Best Algebraic for FE/PE - Need to take the FE/PE? The test is limited to a few models. This is the best algebraic allowed: 1) good menu organization, easy to use 2) 2nd and 3rd degree polynomial solvers 3) 2 and 3 element matrices and vectors 4) numeric derivatives and integrals 5) complex numbers 6) engineering notation 7) constants and conversions All built-in, no need to program. A big plus is cost is nominal. One drawback to this model is it slides all over. Add rubber feet to case bottom as a fix. (see pic)
