Use a spreadsheet formula

A spreadsheet formula calculates from cell references. SUM adds a range; referencing cells makes updates easier than typing a fixed answer.

Worked example

With 100, 150 and 250 in B2:B4, =SUM(B2:B4) returns 500. Changing B3 to 200 updates the result to 550.

Try it yourself

Which formula totals B2 through B6?

Reveal the answer and reasoning

=SUM(B2:B6). Check that the cells contain numbers and that your range includes every intended row.

Try your own answer before comparing it with the worked explanation. This optional check is not a grade or a saved course-completion record.
