A spreadsheet has some values entered: Cell A1 contains 10, cell A2 contains 14, A3 contains 7. You enter in cell A4 the following: =A1+2. Which value is displayed in A4?
The value the play displayed in Cell A4 is 12 because the value in Cell A1 is 10. Since the equation for Cell A4 is A1+2, you replace 10 with Cell A1 to get 10+2. When you add 10 and 2 together, you get your answer of 12.
