HP 35s Scientific ￿Storage Arithmetic, 3-6 Storing Data into Variables

To leave the VAR catalog at any time, press either or . An alternate method to clearing a variable is simply to store the value zero in it. Finally, you can clear all direct variables by pressing (). If all direct variables have the value zero, then attempting to enter the VAR catalog will display the error message “   ”.

If the value of a variable has too many digits to display completely, you can use

Õand Öto view the missing digits.

￿Arithmetic with Stored Variables

Storage arithmetic and recall arithmetic allow you to do calculations with a number stored in a variable without recalling the variable into the stack. A calculation uses one number from the X–register and one number from the specified variable.

￿Storage Arithmetic

Storage arithmetic uses , , , or 

to do arithmetic in the variable itself and to store the result there. It uses the value in the X–register and does not affect the stack.

New value of variable = Previous value of variable {+, –, ⋅, ⎟} x.

For example, suppose you want to reduce the value in A(15) by the number in the X–register (3, displayed). Press A. Now A = 12, while 3 is still in the display.
