A convenient and time-saving feature of Google Sheets is its ability to add, subtract, multiply, and divide numerical information for you. Google Sheets uses mathematical expressions called formulas that make handling these calculations easy. In this lesson, we'll focus on formulas that contain one mathematical operator.
Most of the time, you will be using a cell's address in the formula. This is called using a cell reference. The advantage of using cell references is that you can change a value in a referenced cell and the formula will automatically recalculate. Using cell references in your formulas will make sure the values in your formulas are accurate.
