Getting Down To Work - Microsoft Excel

Look at the bar just below the toolbar.

This is where you will see the cell reference and the actual formula that was automatically created to complete the calculation. 

Looking at these AutoSum formulas is a good way to start learning how to write your own formulas.

If you want to do another simple calculation, do the same selection of numbers and then click on the small arrow below the AutoSum to reveal options such as find the Average or find the Minimum number.

Tip: if you get messed up making a calculation and need to re-do the function, hit the Escape key on your computer.
