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 = X
2
+
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.
(A)
(B)
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.
