Summary: I needed it for a higher math class, but it doesn't have all the functions you need in a graphing calculator. So now I have a very expensive desktop calculator. This calculator will not perform matrix computations.
Summary: I purchased mine for $49. Its suitable for any classes through college algebra. For trig you'll want to upgrade as it doesn't graph polar coordinates though it does convert rectangular to polar and back.
Summary: This calculator has many good features. Large enough for keys to be easily used, but fits in a shirt pocket. Uses two cheap AAA bstteries with a button battery for memory backup. It has a detailed instruction book, But the MEMORY is next to IMPOSSIBLE to access.
