    Storing a value in a variable You can store a value in a variable (that is, assign a value to a variable). Then when you want to use that value in a calculation, you can refer to it by the variable’s name. You can create your own variables, or you can take advantage of the built-in variables in Home view (named A to Z and ) and in the CAS (named a to z, and a few others).

    An introduction to HP apps Much of the functionality of the HP Prime is provided in packages called HP apps. The HP Prime comes with 18 HP apps: 10 dedicated to mathematical topics or tasks, three specialized Solvers, three function Explorers, a spreadsheet, and an app for recording data streamed to the calculator from an external sensing device.

    Variables Variables are placeholders for objects (such as function definitions, numbers, matrices, the results of calculations, and the like). Some are built-in and cannot be deleted. But you can also create your own. Many built-in variables are automatically assigned objects as a result of some operation (such as defining a polar function, performing a calculation, or setting an option).
  • Page 380 To assign an object to a built-in variable, it is important that you choose a variable that matches the type of object. For example, you cannot assign a complex number to the variables A through Z. These are reserved fro real numbers.
