though).There's lots of buzz around the FX-115ES versus the TI-30XS calculator, and if you're heavy into complex numbers and definite integrals, the FX-115ES will shave time and save some paperwork

you can simplify radicals and the numbers are easy to read. .

It's very easy to use and has a big screen so the numbers are easy to see.

Unfortunately if you need the extra features; complex numbers is a BIG ONE, you're out of luck, this one doesn't do it.

ti-30xs is a great calculator, but compared to casio fx-115es, you have to do some thinkingAdvantages of Ti-30xs over casio fx-115es:4 line display, so you can see the previous answersscrolling and copy and paste the answerseasier layout, the buttons are not as cluttered and hard to use as Casio (it's definitely easier to use things from making tables, storing variables ect)stores previous results when you turn on the calcadvantages of Casio fx-115es over ti-30xsWAY more functions, complex numbers, derivatives, integrals, Riemann sum, ect

MultiView offers some improvements to the UI, including handling irrational numbers a lot better (like leaving √2 as √2

complex numbers, solvers, num.calculus, constants library, conversions.

Update: I wanted to add that the Casio FX-115ES is a SCIENTIFIC AND NON-GRAPHING CALCULATOR (same class as the TI-30XS MultiView) that handles everything the TI-30XS Multiview fails to cover such as integrals, derivatives, complex numbers, phasors, different log bases AND matrices
