There are a few ways that you can show formulas in Excel. The easiest way is to press the "F2" key on your keyboard. This will bring up the formula bar, and will show you the formula for the cell that you are currently editing. You can also show formulas by clicking on the "Formula" tab at the top of the Excel window. This will show you all of the formulas that are currently in your spreadsheet. You can also show formulas by clicking on the "View" tab, and then selecting the "Show Formulas" checkbox.
