in B2 is greater than or equal to 10, or Unit Pricein C2 is greater than or equal to $5. So, you use the OR function to check both conditions, and if the result is TRUE, decrease the total amount by 10% (B2*C2*0.9), otherwise return the full price (B2*C2): =IF(OR(B2>=1...
The array formula works exactly the same way asMAX IF with AND logicexcept that you join the criteria by using the addition operation instead of multiplication. In array formulas, addition works as the OR operator: Adding up two arrays of TRUE and FALSE (which result from checking the values...
