Storing and Recalling Numbers

The calculator has ten memories available for use during calculations. These memories are numbered from 1–9 and 0. To store a number in a memory, press :$, followed by

the key representing the memory number. To recall a number stored in a memory, press L

followed by the key representing the memory number. You can use the store and recall functions for these memories any time a number is displayed, or when you wish to enter a number.

For example, to store 15 in memory 1, press 15:$1.

To recall the number in memory 1, press L1.

You can also perform operations to numbers stored in memories. For example, press 5:$2to store 5 in memory 2. To add 12 to the value of memory 2, press

12:$+2. Later on, during a calculation, you can press L2 to recall memory 2. Note how the current value now stored in memory 2 is 17, (5 +12). +-*and /are valid mathematical operations for memories.

To view the stored values in memories 1–9 and 0, press :t, followed by <

or >repeatedly to scroll through each memory starting with memory 1 (Mem 1). Note that in the Memory menu, you can change the value of any memory by selecting the memory

and typing a number followed by the tkey.

Recall Arithmetic

In RPN, typing L+2adds the value of memory 2 to the first level of the stack, but it will not modify the stored value of memory 2. This is useful, as it "saves" one stack level.

You can also use -*and /after L.

Storing and Recalling with Time Value of Money (TVM) Keys

To store the current number in the Time Value of Money (TVM) variables, press :$ followed by the desired TVM key.

To recall the stored value of a TVM variable, press Lfollowed by the key of the desired TVM variable.

Note: pressing Ldoes not calculate the variable; it recalls the current value.
