The picture above gives you a step by step encounter with 4 of Excel calculation functions. The numbers being used are in cells A1, B1 and C1. To make it easier to follow we’ve used the numbers 1, 2 and 3.
The blue cells contain the names of the functions we are using. Below each blue box is what you need to enter in the Formula Bar to make things happen. The next line shows the formula using the actual numbers instead of cell references. The line below that is the calculation that’s taking place, and last of all is the answer produced.
