Back when I was in high school, the TI-84 was one of the best calculator on the market. The TI-84 could do logarithms, the Pythagorean Theorem, the Quadratic Equation, slope-intercepts, etc. Fast forward to about 12 years later and now Texas Instruments has finally added color to their newest generation of TI-84s. The TI-84+ C Silver Edition will have a screen with more than two colors. I’m a bit surprised that TI decided to upgrade an older model, but an upgrade is better than no upgrade.
