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 use2) 2nd and 3rd degree polynomial solvers3) 2 and 3 element matrices and vectors4) numeric derivatives and integrals5) complex numbers6) engineering notation7) constants and conversionsAll built-in, no need to program.A big plus is cost is nominal.One drawback to this model isit slides all over. Add rubber feetto case bottom as a fix. (see pic)

Perfect balance of features and price
I do electronics engineering and I always need to calculate semi-complex stuff. A non scientific calculator is a pain and I find that the ti-84 is a bit much if you’re not doing advanced math or statistics. This calculator is perfect for the bench calculations while designing circuits. Plus because it’s not a small fortune, I carry it around all the time without worry of dropping it etc. my colleagues call me Egon now because I just pull out the calculator and start calculating in random situations and conversations. For the price, you really can’t go wrong.
