Try it yourself
Open a live sheet with this example, and type the formula yourself. It takes a moment to load.
Worth knowing
SUM ignores text and blank cells, so a number stored as text gets skipped without any warning.
Practice it properly
Adding up with SUM gives you real tasks, with your formulas tested on data you haven’t seen.
