Formula: Addition, Subtraction,

Multiplication & Divisionby: Engr. Esmeraldo T. Guimbarda Jr.

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

Activity:

1. Open Microsoft Excel.

Click on Start ►All Programs ► Microsoft Office ► Microsoft Excel or double-click on the Microsoft Excel shortcut on the desktop. This will open a blank workbook in Microsoft Excel.

2. Input contents in sheet1.

● Go to cell A1 and type the value 143● Go to cell B1 and type the value 5254

A B C

1 143 5254

2

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

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

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

● Go to cell A1 and type the value 143● Go to cell B1 and type the value 5254● Go to cell A2 and type the value 1234● Go to cell B2 and type the value 5678

6.● To add A1,A2,B1 and B2, go to cell C1 and type

=A1+A2+B1+B2● To subtract A1,A2,B1 and B2, go to cell C2 and type

=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

=A1/A2/B1/B2
