4 Number Storage and Storage Register Arithmetic

Using Stored Numbers in Calculations

You can store numbers for reuse in several different ways:

•Use ª(Constant) to store a number and its operator for repetitive operations.

•Use 3 Key Memory (s, p, and m) to store, recall, and sum numbers with a single keystroke.

•Use \wand vto store to, and recall from, the 20 numbered registers.

Using Constants

Use ªto store a number and arithmetic operator for repetitive calculations. Once the

constant operation is stored, enter a number and press 4. The stored operation is performed on the number in the display.

Example 1

Calculate 5 + 2, 6 + 2, and 7 + 2.
