The SHARP EL-W516 and the CASIO fx-115ES represent the best examples of the newest incarnation of the scientific calculator which falls somewhere between the capabilities of the scientific and graphing models currently available. They can be thought of as high-end scientific calculators with some of the capabilities normally found only in the graphing models... without the price-tag typical of a graphing calculator. For a very small investment, students now have the advantage of being able to easily explore the mathematical properties of vectors, matrices, simultaneous equation solving, statistics, complex numbers, and calculus operations such as integrals and derivatives.
