Texas Instruments, Graphing Calculator, Black, Color, 1 Each

Visualize concepts clearly and make faster, stronger connections between equations, data and graphs in full color with the TI-84 Plus CE Graphing Calculator. High-resolution backlit display enhances screen readability with 320 x 240 pixels, 140 dpi and 16-bit color on a 2.8" diagonal screen. Distinguish between multiple graphs and plots with color-coded equations, plots and objects. Make graphs easier to read by adding grid lines. Calculator also includes 3MB Flash ROM memory for data archive and Apps storage; 154KB of available RAM memory; internal clock with date and time display; impact-resistant slide case; rechargeable battery; USB unit-to-unit cable and USB unit-to-computer cable.
