5.0 out of 5 stars Best Algebraic for FE/PE
(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } 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)
5.0 out of 5 stars 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.
5.0 out of 5 stars Perfect good
I bought this to my nephew for his high school he likes it he said it’s very good one he ever used
5.0 out of 5 stars Encantado de usarla
Mi hijo la usa a diario en el colegio , recomendada
4.0 out of 5 stars Great and simple college calculator
As a college CS student, this calculator is a must have... the ti 84 is too powerful and has Graphing and programming which are not allowed in 99% of the classes ... so this is a good runner upIt does up to 3x3 matrices , does some integrals and derivittives at a point... does base conversions between decimal hex ,and binary (octal too).It also finds roots for quadratic functions, overall it is easy to use and get the hang of it ...
5.0 out of 5 stars Perfect!
Got this for my daughter who needed it in college for chemistry classes. She said it works great! Would recommend.
