Microsoft Excel Mathematical Formulas: A Guide with Examples

Microsoft Excel is renowned for its powerful mathematical capabilities, enabling users to perform complex calculations and analysis. In this guide, we will explore some of the most commonly used mathematical formulas in Excel and provide examples to help you understand their application.

Basic Arithmetic Operations

Excel supports basic arithmetic operations such as addition, subtraction, multiplication, and division. Here are a few examples:

• Addition: To add numbers in Excel, use the plus sign (+). For example, to add 5 and 3, enter "=5+3" in a cell.
• Subtraction: To subtract numbers, use the minus sign (-). For instance, to subtract 3 from 5, enter "=5-3".
• Multiplication: To multiply numbers, use the asterisk symbol (*). For example, to multiply 5 by 3, enter "=5*3".
• Division: To divide numbers, use the forward slash (/). For instance, to divide 10 by 2, enter "=10/2".

Summing a Range of Values

The SUM function is commonly used to calculate the sum of a range of values. Here's an example:

• To sum a range of numbers, use the SUM function followed by the range. For example, to sum the values in cells A1 to A5, enter "=SUM(A1:A5)".

Average Calculation

The AVERAGE function is used to calculate the average of a range of values. Here's an example:

• To find the average of a range of numbers, use the AVERAGE function followed by the range. For instance, to calculate the average of values in cells A1 to A5, enter "=AVERAGE(A1:A5)".

Maximum and Minimum Values

The MAX and MIN functions are used to find the maximum and minimum values within a range. Here are a couple of examples:

• To find the maximum value in a range, use the MAX function followed by the range. For example, to find the maximum value in cells A1 to A5, enter "=MAX(A1:A5)".
• To find the minimum value in a range, use the MIN function followed by the range. For instance, to find the minimum value in cells A1 to A5, enter "=MIN(A1:A5)".

Exponential and Square Root Functions

Excel provides functions to calculate exponentials and square roots. Here are a couple of examples:

• To calculate the exponential value of a number, use the EXP function. For instance, to calculate e raised to the power of 2, enter "=EXP(2)".
• To calculate the square root of a number, use the SQRT function. For example, to find the square root of 16, enter "=SQRT( 16)".

Trigonometric Functions

Excel supports various trigonometric functions for angles measured in radians. Here are a few examples:

• To calculate the sine of an angle, use the SIN function. For example, to find the sine of 0.5 radians, enter "=SIN(0.5)".
• To calculate the cosine of an angle, use the COS function. For instance, to find the cosine of 1 radian, enter "=COS(1)".
• To calculate the tangent of an angle, use the TAN function. For example, to find the tangent of 0.75 radians, enter "=TAN(0.75)".
