Using the memories
The Scientific calculator has 26 memories, labelled A through to Z. You can
assign a value to each of these memories, and then incorporate the names into
expressions.
To assign a value to a memory:
1. Enter the number to be stored. If the calculation line is displaying an
unsolved expression, the stored value will be the RESULT of the
expression.
2. Tap –>, or select Assign to on Memories on the Too ls menu.
3. Type the memory name. As memory names must be entered as a capital
letter, you will probably need to hold down the letter key for the memory
name.
Note! You can also assign a value to a memory by tapping the Mem button,
highlighting the memory to use and then tapping the Assign to button in the
dialog.
To display the contents of the memories:
• Tap the Mem button, or select Show all on Memories on the Too ls
menu.
To use a stored number in a calculation:
• Type the capital letter corresponding to the memory at the appropriate
point in the calculation. Alternatively, tap the Mem button to display
the list of memories, highlight the memory you want and tap Select.
Note! You can assign values to the memories in any order you like, so use the
names as a reminder of the information they contain. For example, use the T
memory for a rate of taxation, Y for the rate of exchange into yen and so on.
