The MAX function is one of the most commonly used Excel functions when working with numerical data. It helps identify the largest number in a set of values.

The OR function in Excel is a logical function that helps you test multiple conditions at once. It returns TRUE if at least one of the conditions is true and FALSE only if all conditions are false. OR is incredibly useful when paired with other functions like IF, AND, and NOT to create smart formulas and automate decision-making in your spreadsheets.

The IFS function in Excel evaluates a series of conditions and returns a specific value for the first true condition. This makes the IFS function particularly helpful when applying multiple tests, streamlining the process compared to using traditional IF statements.
