Summary: My daughter needed a graphing calculator for Math and I compared prices on other websites with Walmart's price for this item and Walmart had the lowest rate. In addition the calculator met the requirements for her class, and I got free shipping by meeting the $50 minimum, so thanks Walmart!
Summary: I'm a high school math teacher, and I bought one of these two years ago, because many of my students would like a graphing calculator that's less expensive than a TI-84, and I was curious if this fits the bill. It does not. I tried using it for a couple of weeks, but the learning curve was too steep, and it never came close to being as useful as a TI-84. If a math teacher has trouble using this calculator, your kid will be seriously hampered by it.
