Model : CASIO fx-570MS, CASIO fx-991MS
CALC memory(CALC button) 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 it's variables and calculate a result quickly and easily.
You can store a single mathematical expression with up-to 79 steps.CALC memory can only be used in the COMP and COMPLX Mode.
Example: Calculate the result of y=a2+b2+c2+3abc when
a) a=5,b=2,c=1 (Ans:60)
b) a=3,b=7,c=4 (Ans:326)
Solution:
Step 1.(Input and Store Function)
for more values to input follow step 3.
The expression you store is cleared whenever you start another operation,change to another mode or turn off the calculator.You can also use D,E,F,X.Y in the expression.

Solution:
Step 1.(Input and Store Function)
ALPHA >> (-) >> x2 >> + >> ALPHA >> .,,,(Degree button) >> x2 >> + >> ALPHA >> hyp >> x2 >> + >> 3 >> ALPHA >> (-) >> ALPHA >> .,,, >> ALPHA >> hyp >> CALC
Step 2.(Input Values a=5,b=2,c=1)
5 >> = >> 2 >> = >> 1 >> =
Step3.(Input Values a=3,b=7,c=4)
CALC >> 3 >> = >> 7 >> = >> 4 >> =
