When you first open a new Excel file you will get a blank document populated with lots of blank rectangles. Each rectangle is called a cell. The page should look like this:
If you single-click a cell then you select one of the cells which should look like the picture below.
When you double-click into a cell you can then enter either text or numbers. In order to create a formula you have to put an equals sign (=) followed by either text or numbers. For example.
Dollar-signs ($) can be used to lock a cell that is being referenced in a formula either vertically, horizontally or both.
In the next post, I will be talking about the use of the dollar-sign and give examples of using it.
