SUMIF vs SUMIFS in Excel, illustrated with one condition and multiple conditions feeding into sum symbols

IF and AND in Excel checking sales and rating conditions to return Yes or No

If you want to check whether two or more conditions are true at the same time, a plain IF function won’t get you there. For example, you may want to pass a student only if they scored at least 50 and also have 75% attendance. That’s because IF only tests one condition at a time. …
