There are four different types of calculation operators: arithmetic, comparison, text concatenation and reference.

**Arithmetic Operators**

To perform basic mathematical operations such as addition, subtraction or multiplication, combine numbers and produce numeric results, arithmetic operators are used.

Arithmetic | Operator Meaning |

+ (plus sign) | Addition |

– (minus sign) | Subtraction Negation |

* (asterisk) | Multiplication |

/ (forward slash) | Division |

% (per cent sign) | Per cent |

* (caret) | Exponentiation |

**Comparison Operators**

You can compare two values with the following operators. When two values are compared by using these operators, the result is a logical value either TRUE or FALSE.

Comparison Operator | Meaning |

= (equal sign) | Equal to |

> (greater than sign) | Greater than |

< (less than sign) | Less than |

> = (greater than or equal to sign) | Greater than or equal to |

< = (less than or equal to sign) | Less than or equal to |

<>, ! = (not equal to sign) | Not equal to |

**Text Concatenation Operator**

Use the ampersand (&) to concatenate (combine) one or more text strings to produce a single piece of text.

Text Operator | Meaning |

& (ampersand) | Connects or concatenates, two strings to produce one continuous text value. |

**Reference Operators**

To combine the range of cells for various calculations reference operator are used.

Reference Operator | Meaning |

: (colon) | Range operator, which produces one reference to all the cells between two references, including the two references. |

, (comma) | Union operator, which combines multiple references into one reference. |

(space) | Intersection operator, which returns a reference to the cells common to the ranges in the formula. In this example cell C7 is found in both ranges, so it is the intersection. |

**Order of Evaluation of Formulas**

Results provided by the formulas, are dependent on the preferences of operators. Preferences of operators are as follows:

: Range reference

– Negative Number

% Percentage

^ Exponentiation

* Multiplication

/ Division

+ Addition

– Subtraction

& Concatenation

= < > or < = or >= or > or < Comparison

**Displaying Formulas**

To show the formula which is entered in a cell, the steps are as follows:

Step 1 Select the cell where formula has entered. ‘

Step 2 Click Formulas tab → Formula Auditing group → Show Formulas.

**Functions**

A function is a **predefined formula** that performs calculations using specific values in a particular order, e.g. SQRT (), LOWER (), etc. Functions make it easy to perform common calculations on data.

In order to use these functions correctly, you need to understand the different parts of functions.

**The Parts of Function**

Each function has a specific order called “syntax”, which must be followed for the function to work correctly. The basic syntax to create a formula with function is:

• to insert an equal sign (=).

• a function name (for e.g. SUM).

• an argument that contain the information related to formula to calculate such as range of cell references.

**Function Categories**

In MS-Excel, functions are categorised into following groups:

1. **Text Functions** These functions are used to remove extra characters e.g. TRIM, CLEAN, etc.

2. **Logical Functions** These functions are performed boolean operations on given data e.g. AND, OR, NOT. etc.

3. **Date and Time Functions** These functions are used to create date and time.

e.g. DATE, TIME, DATEVALUE, etc.

4. **Financial Functions** These are used to calculate financial calculations such as investment valuations, interest rate.

e.g. FV, PV, RECEIVED, etc.

5. **Maths and Trigonometry** These functions perform mathematical calculation including arithmetic, sum, products and trigonometry.

e.g. PRODUCT, MOD, TAN, etc.

6. **Information Functions** These functions provide information about error in formula or data value.

e.g. ISERROR, ISNA, etc.

7. **Engineering Functions** These functions are used to perform calculations related to complex numbers, bessel functions.

etc. e.g. CONVERT, BESSELI, etc.

8. **Lookup and References Functions **These functions are used to perform operation on data array.

e.g. VLOOKUP, MATCH, etc.

9. **Database Functions** These functions are used to calculate the average, maximum or minimum data from the database list.

e.g. DMAX, DCOUNT, etc.

10. **Statistical Functions** These functions are used to find the largest and the smallest value from a list of data values.

e.g. MAX A, LARGE, etc.

Some useful functions in Excel are listed below:

Function | Description |

SUM | Returns the sum of a list of supplied numbers. |

AVERAGE | Returns the average of a list of supplied numbers. |

MAX | Returns the largest value from a list of supplied numbers. |

MIN | Returns the smallest value from a list of supplied numbers. |

FACT | Returns the factorial of a given number. |

INT | Rounds a number down to the next integer. |

ROUND | Rounds a number up or down, to a given number of digits. |

TRIM | Removes duplicate spaces and spaces at the start and end of a text string. |

FIXED | Rounds a supplied number to a specified number of decimal places and then converts this into text. |

VALUE | Converts a text string into a numeric value. |

MID | Returns a specified number of characters from the middle of a supplied text string. |

AND | Tests a number of user-defined conditions and returns TRUE if ALL of the conditions evaluate to TRUE or FALSE otherwise. |

OR | Tests a number of user-defined conditions and returns TRUE if ANY of the conditions evaluate to TRUE or FALSE otherwise. |

FALSE | IF Tests a user-defined condition and returns one result if the condition is TRUE and another result if the condition is FALSE. |

DATE | Returns a date, from a user-supplied year, month and day. |

TIME | Returns a time, from a user-supplied hour, minute and second. |

VLOOKUP | Looks up a supplied value in the first column of a table and returns the corresponding value from another column. |

INDEX | Returns a reference to a cell (or range of cells) for requested rows and columns within a supplied range. |

TRANSPOSE | Performs a transpose transformation on a range of cells (i.e. transforms a horizontal range of cells into a vertical range and vice-versa). |

SUMIF | Adds the cells in a supplied range, that satisfy a given criteria. |

SUBTOTAL | Performs a specified calculation (e.g. the sum, product, average, etc.) for a supplied set. |

**Charts**

Charts are the graphical and pictorial representation of worksheet data. Microsoft Excel supports charts, graphs or histograms generated from specified groups of cells. The generated graphic component can either be embedded within the current sheet, or added as a separate object.

Different types of chart are as follows:

1. Column

2. Line

3. Pie

4. Area

5. Scatter

6. Stock

7. Surface

8. Doughnut

9. Bubble

10. Radar

**Components of a Chart**

A chart consists of the following components:

**X-axis** is a horizontal axis known as category axis.

**Y-axis** is a vertical axis known as values axis.

**Data Series** is the set of values you want to plot in the chart.

**Chart Area** is the total area of the chart.

**Legends** is a unique color or pattern, which helps you to identify an individual data series.

**Chart Title** is the descriptive text aimed at helping user identify the chart.

**Axis Titles** are the titles given to three axis i.e. X, Y, Z.

**Gridlines** are horizontal and vertical lines which are inserted in the chart.

**Data Label** provides additional information about a data marker.

**Creating Chart**

Steps to create a chart are as follows:

Step 1 Select the data you want to summarise visually and then click on the Insert tab.

Step 2 In the charts group, click the type of chart you want to create, to display the available chart subtypes.

Step 3 Then, select anyone of them by clicking it.

Step 4 After selecting click OK button.
