Hey guys.

What would be the best graphing calculator that could do everything?? What i mean by everything is from basic algebra to calculus 3 and be on. From General Chemistry 1 to Organic Chemistry 2 and be on. From Basic Physics to Quantum Physics, String theory and be on.

Would it be a TI-83 Silver?? Well christmas is coming up soon and if i have the money i'm going to buy one. I'm starting off with the basic math since September and i have to continue until Calculus 3 or higher. My field is not math but my field or major is offered by the mathematics department. Please reply back. Thanks guys.
