Using CALC

•You can store a single mathematical expression, with up to 99 steps. Note that the command can only be used in the COMP Mode.

•The command lets you temporarily store a mathematical expression that you need to perform several times. Once you store an expression, you can recall it, input variables, and calculate quickly.

•The following shows the kind of expressions that you can save with the function.

A.Expressions: 2X + 3Y, 2AX + 3BY + C

B.Multiple instructions: X + Y: X(X + Y)

C.Equations with unique variable on left and one

expression contains variables on right: A = B+C, Y = X2 +

X + 3 (note: we must use specific [=] key to input equality symbol of the equation).

•The variable input screen shows the current value from the assigned variables.

•Wherever you start a new calculation, ensure that the stored expression is cleared by changing the mode or by pressing the key.

Example: To store 3A + B and then substitute the variables with the following values (A:B) = (5:10). Calculate the value of the expression.

Metric Conversion

•The calculator's built-in metric conversion commands make it easy to convert values from one unit to another. You can use the metric conversion commands in any calculation mode except for BASE-N and TABLE.
