CASIO PRIZM FX-CG50 Color Graphing Calculator,Black & White,7.21Wx10.32Lx2.05H

Compared to other calculators in the same range e.g. TI Nspire CXII CAS. Pro: - powerful graphing and CAS functions, especially the ability to edit equations and automatically cascade the edits/results to all entries below - the D pad is perfect! - easy to hold and feels sturdy - display is bright and very easy to read Cons: - certain functions can be time consuming to find in the menus via the OPTN and VARS keys with FN keys, unless you memorized the sequence of key presses, still the menu tree feels somewhat cluttered - no true symbolic CAS, i.e. no differentiation/integration to produce symbolic results, but point-wise derivatives/integrals, which is OK for most applications but still... not a real CAS like the TI NSpire CAS - the catalog does not describe the functions, but rather offers a QR code to scan with a phone to pull up the help page online, which is OK but it would have been nice to show at a minimum the syntax and parameters
