Audience Relations, CBC P.O. So what do we learn? The = equals symbol is used to show that the values on either side of it are the same. By default, new formulas use relative references, so you may need to switch them to absolute references. In some cases, the order in which a calculation is performed can affect the return value of the formula, so it's important to understand how the order is determined and how you can change the order to obtain the results you want. 3-D references cannot be used in array formulas.
