## Zoom Math 400 Makes Algebra Easy

Even without a Registration Key, Zoom Math 400 makes calculations easy. Fractions look like fractions and exponents look like exponents. Everything looks right. An unregistered copy of Zoom400 works just like an unregistered copy of Zoom200 or Zoom300: It does everything App4Math can do, plus a little bit of graphing and a little bit of algebra.

After you buy a Registration Key, Zoom Math 400 can do everything that any previous Zoom Math product can do. It can show problems in correct math notation like App4Math, graph equations like Zoom Math 100, solve Algebra 1 problems like Zoom Math 200, and solve Algebra 2 problems like Zoom Math 300.
