**Introduction**

Microsoft Excel is a spreadsheet program that is used to record and analyses numerical data. It is designed to perform calculations, analyze and visualize data in a spread-sheet. Alphabetical letters are usually assigned to columns and numbers are usually assigned to rows. The point where a column and a row meet is called a cell. The address of a cell is given by the letter representing the column and the number representing a row.

**Using Basic Formulas and Calculations**

One of the most powerful feature in Excel is the ability to calculate numerical information using formulas. Just like a calculator, Excel can add, subtract, multiply and divide. A formula uses standard mathematical symbols to operate on cell addresses and/or numbers.

A formula can be a combination of values (numbers or cell references) and mathematical operators into an algebraic expression.

**Mathematical operators**

MS-Excel 2013 user standard operators for formulas, such as:

+ For addition

- For Subtraction

* For multiplication

/ For division

% For Percentage

^ For exponentiation (power)

All formulas in MS-Excel must begin with an equal sign (=)

Some examples of formulas:

If A1 = 5, B1 = 7, C1 = 4, D1 = 2 then

v =B1 + C1 will give result as 7 + 4 = 11

v =Al * C1 + B1 - Dl will give result as 5 * 4 + 7 - 2 ='25

v =((Al * C1)/Al) will give result as (5 * 4)/5 = 20/5 = 4

**There are some basic functions in Excel also:**

v Sum (): The sun function is used to add all the numbers in a range of cells.

Syntax =sum (range of cells)

Example (B2:D2)

Result 190

v Average (): The average function is used to get the average of the numbers.

Syntax = Average (range of cells)

Example (B2:D2)

Result 63.3

v Min (): The Min function is used to get the minimum of the numbers.

Syntax = min (range of cells)

Example = (B2:D2)

Result = 6

v Max (): The Max function is used to get the maximum of the numbers.

Syntax = max (range of cells) Example max (B2:D2)

Result =89

**Printing Worksheets**
