2. Using Formula in Excel
To compute for two or more numbers in Excel you need to
create a formula. Two important points to remember about
Excel formulas:
● formulas in Excel always begin with the equal sign ( = )
● the equal sign always goes in the cell where you want the
answer to go

3. Activity:
1. Open Microsoft Excel.
Click on Start ►All Programs ► Microsoft Office ►

5. 3.
● To add both A1 and B1, go to cell C1 and type =A1+B1
● To subtract A1 from B1, go to cell C2 and type =A1-B1
● To multiple A1 from B1, go to cell C3 and type =A1*B1
● To divide A1 from B1, go to cell C4 and type =A1/B1

6. 4. Try to change the value of A1 & B1 several times and see what
happens.

7. 5. Lets try more than 2 variables. Lets user A2 and B2.

=A1-A2-B1-B2
● To multiple A1,A2,B1 and B2, go to cell C3 and type
=A1*A2*B1*B2
● To divide A1,A2,B1 and B2, go to cell C4 and type
