Less expensive, better features, faster, and more accurate than TI
6 days ago
Summary: Even though this calculator is less expensive than the TI-83 or 84 it is significantly better at life. It doesn't have a computer algebra system (CAS) so it's a bit unfair comparing it to the TI-89 or Nspire. That said, this baby has features that makes the TI-89 blush. I can calculate x intercepts at least twice as fast as my TI-89 toting classmates.
Summary: The calculator was purchased for my younger daughter doing IB1 math this year. She finds it very useful. My elder daughter also bought this calculator 2 years ago, again for IB math and IB economics. She is now in College and can't live without it!!
Summary: Product was sent out in a timely manner. Received when stated. And arrived in excellent condition and packaging. Only complaint is extra money charged to my account for online purchase (card verification). Calculator way more intelligent than me!!!!!!
Great for solving engineering problems directly. Excellent tool!

Summary: very potent & powerful tool. Still exploring it's capabilities but I am very impressed so far. Using this calculator for integration and derivatives are straightforward because the functions are pre-programmed into it. Solving difficult problems in physics, chemistry & statics are easy.
