Power
In complex calculations, there is more than one part to the formula, the order of the calculations is
from left to right, but any part of the formula in parentheses will be calculated first.

Microsoft Excel multiplies the cell by 100 and displays the result with the percentage sign.
1. Click cell B3 and type =B2/D2.
2. Click cell C3 and type =C2/D2.
3. Select the cells which contain the
numbers you want to format, in this
