Using Formulas

Writing Formulas Click the cell where you want the answer to appear In Excel all formulas being the with equal sign (=)

Simple Formulas + - * / ^ Add =sum(b3+b4) Subtract =(b3-b4) + - * / ^ Add =sum(b3+b4) Subtract =(b3-b4) Multiply =(b3*b4) Divide =(b3/b4) Power =(b2*b3)^3

Completing the Formulas Once you have completed the formula you must click ‘enter’ in order for it be done. The result will appear. Note: If you have multiple columns with the same formula you can copy and paste the formula to the other columns and save yourself some time!

Complex Formulas Complex formulas: formulas where more than one function is being carried out in one cell: Example: =(b3-b4/3)^2

Using References Instead of Values Cell references - using cell addresses instead of whole numbers Avoiding errors Reflecting changes
