6-12 Entering and Evaluating Equations

 If the equation is an assignment, only the right–hand side is evaluated. The

result is returned to the X–register and stored in the left–hand variable, then

the variable is viewed in the display. Essentially,

 finds the value of

the left–hand variable.

 If the equation is an equality or expression, the entire equation is evaluated

— just as it is for

. The result is returned to the X–register.

Example: Evaluating an Equation with ENTER.

Use the equation from the beginning of this chapter to find the volume of a 35–mm

diameter pipe that's 20 meters long.

Using XEQ for Evaluation

If an equation is displayed in the equation list, you can press  to evaluate the

equation. The entire equation is evaluated, regardless of the type of equation. The

result is returned to the X–register.
