    • 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 up It 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 ... ... show more
