Mastering Basic Formulas and Functions in Excel

Introduction

In our previous post, we covered the basic interface of Excel. Now, let’s dive deeper into one of its most powerful features: formulas and functions. These tools allow you to perform calculations, manipulate data, and automate tasks.

Basic Formulas

• Arithmetic Operators:
  • Addition: +
  • Subtraction: –
  • Multiplication: *
  • Division: /
• Cell References: You can refer to cells in formulas using cell references (e.g., A1, B2).
• Order of Operations: Excel follows the standard order of operations: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction (PEMDAS).

Common Built-in Functions

• SUM: Adds a range of cells.
• AVERAGE: Calculates the average of a range of cells.
• COUNT: Counts the number of cells in a range.
• MAX: Returns the largest value in a range.
• MIN: Returns the smallest value in a range.
• IF: Performs a logical test and returns one value if the test is true, and another value if the test is false.
• VLOOKUP: Searches for a value in a table and returns a corresponding value from a specified column.  

Creating Formulas

1. Select the cell where you want to enter the formula.
2. Type the equal sign (=) to start the formula.
3. Enter the formula using cell references, functions, and operators.
4. Press Enter to complete the formula.

Example:

To calculate the total cost of items in cells A2, B2, and C2, you can use the following formula:

=SUM(A2:C2)

Tips for Effective Formula Usage:

• Use absolute and relative cell references: Absolute references ($A$1) keep the cell reference fixed, while relative references (A1) adjust as the formula is copied.
• Use the AutoSum feature: Quickly sum a range of cells by selecting the cells and clicking the AutoSum button.
• Check for errors: Use the formula auditing tools to identify and correct errors in your formulas.
