To enter a formula on the Excel worksheet, click in the desired cell.
Type an equal sign, the correct formula, and click the check mark.
Here is an example of a formula that multiplies the number in cell C2 by 5 x 10 3 and divides by 2.
= (C2*5*10^3)/2
Then you can highlight the rest of the column and click "fill down," and it will do the same to the rest of the column, using the correct C3, C4, etc.
