This is a great calculator. I recently bought one and it works great. I would recommend it to anyone taking Algebra I or higher math like Trig or Calc. This has pretty cool statistics functions too, so its pretty cheap for what you get. You can have up to 99 exponents and it also has cube roots, something which normal calculators lack. The bad thing about this calculator is that its pretty heavy and it takes some pretty weird hard-to-find batteries.
