Excel usually allows you to do the different calculation in a few different ways. It’s also the case if you want to do simple arithmetic operations such as addition or subtraction.
Take a look at the following example.
Let’s add and subtract numbers in column A (A2:A5) to the value in cell C2. The most straightforward way is to add and subtract these numbers one by one.
