Wonderful for All Math Uses

This calculator is one of the best available to buy. It's worth every penny I paid for it. You can do everything from simple addition to calculus and more with it. My friends and I have even found that they're great to use for writing messages and drawing pictures. The color options allow you to see differences on charts and graphs more easily and the large display makes it easier to read. Being able to bring up past calculations is a plus as well. It saves a lot of time when you're in a hurry. The only real drawback that I can see is that if you're not careful you can become dependent on it since it does just about everything for you.
