1. SUM

The SUM function is the first must-know formula in Excel. It usually aggregates values from a selection of columns or rows from your selected range.
=SUM(number1, [number2], …)

Example:
=SUM(B2:G2) – A simple selection that sums the values of a row.
=SUM(A2:A8) – A simple selection that sums the values of a column.
=SUM(A2:A7, A9, A12:A15) – A sophisticated collection that sums values from range A2 to A7, skips A8, adds A9, jumps A10 and A11, then finally adds from A12 to A15.
=SUM(A2:A8)/20 – Shows you can also turn your function into a formula.
