Excel is logical. Which means that logical functions (or “formulas”) are a key part of using this software. Learn to speak the language of Excel by understanding decision-making, logical functions. These check if a condition is true or false and can also be used to combine multiple conditions together. The basic building block of these is the IF function, which will be covered in-depth. Then you’ll add additional functions such as nested IFs, AND, OR, COUNTIF, ISBLANK, ISERROR, ISERR, and ISNUMBER. Learn the evaluation power of Excel by understanding logical functions and how they can be used and incorporated into your daily work.
