Barbara, Orlando AddedMonday, August 25, 2014 at 11:28 AM Which type of calculator is best for school? Hello! Im currently in college and I wanted to know which calculator is going to be more useful for engineering? I have read that most people use the TI-89 but in a lot of websites they say that the TI-Nspire is way better. If you know which one is better for engineering classes please let me know!

You will need a good graphing calculator, but the type will depend upon you and your teachers. See what your classmates have, and if you can try them both out before you make a purchase.

You need to ask your professors and also, remember you need to learn how to used it. So, don't go to advanced or complicated that it will be a problems to used it
