correct entry. You can also clear an error by pressing [ CL ] and
then re-entered the values and expression from the beginning.
See Example 3.
Memory Calculations
z
Press [ M+ ] to add a result to running memory. Press [ M– ] to
subtract the value from running memory. To recall the value in
running memory, press [ MRC ]. To clear running memory, press
[ MRC ] twice. See Example 4.
z
The calculator has eight memory variables for repeated use :
A, B,
C, X, Y, X1, X2, PROG
. You can store a real number in variables
A,
B, C, X, Y, X1, X2
and an expression in
PROG
. See Example 5.
* [ P/V RCL ] recalls all variables.
* [ SAVE ] lets you store values to variables.
* [ 2nd ] [ RECALL ] recalls the value of variable.
* [ 2nd ] [ CL-VAR ] clears all variables except
PROG
.
* [ 2nd ] [ CL-PROG ] clears the contents of
PROG
.
Order Of Operations
Each calculation is performed in the following order of precedence :
1) Expression inside parentheses.
