•You can also edit expressions on the display and per- form other multi-statement operations. For more details about using multi-statements, see “Multi-statements” in the separate “User’s Guide.”

•Only the expressions in replay memory starting from the currently displayed expression and continuing to the last expression are copied. Anything before the displayed expression is not copied.

kCALC Memory

COMP CMPLX

•CALC memory lets you temporarily store a mathematical expression that you need to perform a number of times using different values. Once you store an expression, you can recall it, input values for its variables, and calculate a result quickly and easily.

•You can store a single mathematical expression, with up to 79 steps. Note that CALC memory can be used in the COMP Mode and CMPLX Mode only.

•The variable input screen shows the values currently assigned to the variables.

•Example: Calculate the result for Y = X2 + 3X – 12

when X = 7 (Result: 58), and when X = 8 (Result: 76).

(Input the function.)

pyp up xK + 3 p x, 12

(Store the expression.)

•Note that the expression you store is cleared whenever you start another operation, change to another mode, or turn off the calculator.

kSOLVE Function

The SOLVE function lets you solve an expression using variable values you want, without the need to transform or simply the expression.

•Example: C is the time it would take for an object thrown straight up with initial velocity A to reach height B.
