microsoft excel courses in london - Formulas

Hi Jenni,

You can use the sum function to add up a range of cells, for example,
=SUM(A1:A15)

or you can add up numbers in a whole column if you type the formula =SUM(A:A), this would be all the numbers in column A. However if you use the second option your formula must be in any other cell except column A.

Hope that helps
