A Inserting Ans into a Calculation Manually

You can insert Ans into a calculation at the current cursor location by pressing 1-(Ans).

Example 1: To use the result of 123 + 456 in another calculation as shown below

123 + 456 = 579 789 – 579 = 210

789-1-(Ans)E

Example 2: To determine the square root of 32 + 42 and then add 5 to the result

b

3x+4xE

!1-(Ans))+5E

k Using Independent Memory

Independent memory (M) is used mainly for calculating cumulative totals.

A Adding to Independent Memory

While a value you input or the result of a calculation is on the display, press l to add it to independent memory (M).

Example: To add the result of 105 ÷ 3 to independent memory (M)

b

105/3l

A Subtracting from Independent Memory

While a value you input or the result of a calculation is on the display, press 1l(M–) to subtract it from independent memory (M).
