To do this, use the SUMIFS function. It adds numbers from one column if adjacent cells meet your criteria.

A common mistake is mismatched range sizes. If you sum column C2:C100, the criteria range must be the same size.

When there are many conditions, the formula becomes cumbersome. For complex analysis, it's easier to use ready-made examples of the SUMIFS formula with multiple conditions.
