Parents: If you're going to buy your child a graphing calculator for school, DON'T insult his/her intelligence with this limited function calculator. Go with a TI-86 or TI-89 as it will serve him/her well through into college. What this means is you save money by purchasing one calculator that will be useful for SATs, GREs, AP tests, high school, algebra, calculus 1-3, college, etc...
