# The Basics of Formulas in MS Excel

Microsoft Excel is a powerful tool that allows users to perform complex calculations, analyze data, and create visually appealing charts and graphs. One of the key features that sets Excel apart from other spreadsheet software is its ability to use formulas. Formulas in Excel are a combination of mathematical operators, cell references, and functions that perform calculations and return results. In this article, we will explore the basics of formulas in MS Excel, including how to start a formula, common operators and functions, and some practical examples.

## Starting a Formula in MS Excel

Formulas in Excel always start with an equal sign (=). This tells Excel that the following characters are part of a formula and should be evaluated as such. After the equal sign, you can enter a combination of numbers, cell references, operators, and functions to create your formula.

Let’s take a look at a simple example. Suppose you have a spreadsheet with two columns, A and B, and you want to add the values in cells A1 and B1. To do this, you would start by typing the equal sign, followed by the cell references:

```=A1+B1
```

Once you press Enter, Excel will evaluate the formula and display the result in the cell where the formula was entered.

## Common Operators in Excel Formulas

Excel supports a variety of mathematical operators that can be used in formulas. Here are some of the most commonly used operators:

• Addition (+): Adds two or more values together. For example, `=A1+B1` adds the values in cells A1 and B1.
• Subtraction (-): Subtracts one value from another. For example, `=A1-B1` subtracts the value in cell B1 from the value in cell A1.
• Multiplication (*): Multiplies two or more values together. For example, `=A1*B1` multiplies the values in cells A1 and B1.
• Division (/): Divides one value by another. For example, `=A1/B1` divides the value in cell A1 by the value in cell B1.
• Exponentiation (^): Raises a number to a power. For example, `=A1^B1` raises the value in cell A1 to the power of the value in cell B1.

These operators can be combined in various ways to create more complex formulas. For example, you can use parentheses to control the order of operations:

```=(A1+B1)*C1
```

In this example, Excel will first add the values in cells A1 and B1, and then multiply the result by the value in cell C1.

## Using Functions in Excel Formulas

In addition to mathematical operators, Excel also provides a wide range of built-in functions that can be used in formulas. Functions are predefined formulas that perform specific calculations or tasks. They can save you time and effort by automating complex calculations.

Excel functions are typically written in uppercase letters and followed by parentheses. The arguments, or inputs, for the function are enclosed within the parentheses. Here are a few examples of commonly used functions:

• SUM: Adds up a range of cells. For example, `=SUM(A1:A5)` adds the values in cells A1 to A5.
• AVERAGE: Calculates the average of a range of cells. For example, `=AVERAGE(A1:A5)` calculates the average of the values in cells A1 to A5.
• MAX: Returns the largest value in a range of cells. For example, `=MAX(A1:A5)` returns the largest value in cells A1 to A5.
• MIN: Returns the smallest value in a range of cells. For example, `=MIN(A1:A5)` returns the smallest value in cells A1 to A5.
• IF: Performs a logical test and returns one value if the test is true, and another value if the test is false. For example, `=IF(A1>B1, "Yes", "No")` checks if the value in cell A1 is greater than the value in cell B1 and returns “Yes” if true, and “No” if false.

These are just a few examples of the many functions available in Excel. You can explore the full list of functions by clicking on the “Formulas” tab in the Excel ribbon and selecting “Insert Function.”

## Practical Examples

Now that we have covered the basics of starting a formula, using operators, and incorporating functions, let’s look at some practical examples to illustrate how formulas can be used in Excel.

### Example 1: Calculating Total Sales

Suppose you have a spreadsheet with a list of products in column A and their corresponding sales quantities in column B. You want to calculate the total sales by multiplying the quantity sold by the price per unit (stored in column C) for each product. To do this, you can use the following formula:

```=B1*C1
```

This formula multiplies the value in cell B1 (quantity sold) by the value in cell C1 (price per unit) to calculate the total sales for the first product. You can then copy this formula down the column to calculate the total sales for the remaining products.

### Example 2: Applying a Discount

Suppose you have a spreadsheet with a list of products in column A and their corresponding prices in column B. You want to apply a 10% discount to each price and calculate the discounted price. To do this, you can use the following formula:

```=B1*0.9
```

This formula multiplies the value in cell B1 (original price) by 0.9 (10% discount) to calculate the discounted price. You can then copy this formula down the column to calculate the discounted price for the remaining products.

## Summary

Formulas are a powerful feature in MS Excel that allow users to perform calculations, analyze data, and automate complex tasks. They always start with an equal sign (=) and can include mathematical operators, cell references, and functions. By understanding the basics of formulas, including how to start a formula, common operators
