FX-87

An FX-87 is a type of calculator. It is mainly used in Math or Science classes to help do calculations. It helps you to solve equations and complex problems much more quickly than you could by doing them by hand. It does arithmetic (additions and subtractions), algebra (like fractions, exponents and equations) and calculus (finding rates of change) operations. You can also do advanced operations like graphical representations, statistical problems and plotting graphs with it.
