Using Maths Actions

Maths Actions are available on Notes, Scratchpad and Calculator pages.

When you display the context menu for a selected expression or equation, the menu may include a Maths Actions submenu that lists the available actions. Each action might prompt you for any needed parameters.

The specific maths actions listed depend on:

The type of expression or relation.
The operating system in use (Numeric, Exact Arithmetic, or CAS).
Any restrictions imposed by an active Press-to-Test session.
