    • Good All-Around Scientific Calculator
Color: Black
Coming from the TI calculators, there was a little bit of a learning curve to using it, but I do feel satisfied with it. I would treat this calculator like an advanced version of a TI-30 Scientific calculator with some basic graphing and calculus functions of a TI-83. Graphing: It only allows 2 functions to be plot at a time but there is a built in function that shows you how to graph. It has functions so you can use the graphs analytically, like Tracing and a solver, etc... It also has the ability to plot statistical data and plot regression lines, which is pretty useful. Calculus: There is only a numerical solver for both derivation and integration, so this would be handy for some quick calculations. Since the input is scrolling and a single line, like the TI-30, I am hesitant to use this for lengthy equations due to human error. Statistics: To me, I think this is a stronger area for the calculator because it allows the user to input data points and work with standard deviations and regressions. As I mentioned above, the calculator has the ability to graph the data points and display different types of regressions. It can also show the data distributions as bar or line graphs. Conversions: Another helpful tool for some will the Decimal, Hexadecimal, Octal and Binary Converters. There are also some logical operators like AND, OR, XOR, etc... that would be helpful for Electrical or Computer Engineers. ... show more

Love this calculator. It's not solar powered though. But great functionality except I wish the screen lit up. It's accurate. Lightweight.

    • Ok
Color: Black
The overall quality is ok. Cover - The calculator cover doesn’t fit. It’s too big. It falls off which renders it useless. Can’t protect the calculator while in bag. Buttons - The buttons are loose and rattle which give it a cheap feel. Display - the display is ok. Directions - the directions towards how to use functions are quick, hasty, and require a lot of trial and error. Price - Great but it gets you marginal quality. Overall - it gets the job done. ... show more
