HP 40gs Graphing Calculator with CAS

Product Description The HP 40gs is Hewlett-Packard's graphing calculator targeted at students in high school who need a computer algebra system (CAS). It is the successor to the 40G, and 38G, and it is sold alongside the 39gs (equivalent with infrared but without CAS). The 40gs is aimed directly at the TI-83 and TI-84 graphing calculators, but it is a much better choice, as it is cheaper, more powerful, and easier to use. It also provides a good alternative to the TI-89. It has a high-resolution screen and, unique among HP calculators, provides split-screen graphing and has electronic lessons known as "aplets".
