Graphing calculators are ideal for student use in math and science classes from middle school to college.

What Customers Are Saying

The calculator was safely bundled in bubble wrap, it came with batteries and worked straight out of the box! A great purchase if you are trying to save money (my college bookstore sells a TI-83 Plus for $130) without compromising quality.

Elai

After 7 years of use I can report durability, ease of use, and applicability from algebra 1 through calculus. This most recent purchase was for the plus with color and my algebra 2 student reports he likes the color graphing quite a bit. 

Thomas

I love this product so much that I named her Tiffany. Trust me when I tell you that I didn't name any of the calculators I bought before Tiffany. If it were not for Tiffany, I would not have made an A in my pre-stats AND stats classes.
