Adding numbers is probably the most basic operation you'll do, and Excel makes it super simple. To add two or more numbers, you'll use the plus sign (+). For example, if you want to add the values in cells A1 and B1, the formula would be =A1+B1. You can also add more cells: =A1+B1+C1+D1. Excel will add the values in each cell together and display the result in the cell where you entered the formula. This is the simplest formula, but it is super helpful. And one of the most used formulas out there. This operation forms the basis of many more complex calculations, making it an essential tool in your Excel arsenal. This basic function is the foundation for almost all financial and accounting applications. Now you know how to add numbers, you can start building more complicated formulas!

2. Subtraction (-)

Subtraction is just as easy as addition. To subtract one number from another, use the minus sign (-). For example, to subtract the value in cell B1 from the value in cell A1, the formula would be =A1-B1. This is a straightforward formula to calculate differences. This could be useful to find, for example, the profit of a company. Let's say you have the cost price and the selling price, and you can calculate the difference. If it's a positive number, you've made a profit, if it is a negative number, you've made a loss. The Subtraction formula is fundamental for a variety of tasks, from calculating differences between values to managing budgets and analyzing financial performance. This is the cornerstone for performing more complex mathematical operations.

3. Multiplication (*)

Multiplication uses the asterisk symbol (*). To multiply two or more numbers, use this symbol between the cell references. For example, to multiply the values in cells A1 and B1, the formula would be =A1*B1. You can also multiply more cells: =A1*B1*C1*D1. This formula is often used for calculating total costs, revenues, or any other value that involves multiplying two quantities together. This is a very helpful feature for any kind of calculations that require multiplying. Think about calculating sales, calculating volume or area, and so on. Understanding and implementing multiplication in Excel opens up a wide range of possibilities for data analysis and financial modeling. Let's move on to the next basic operation.

4. Division (/)

Division uses the forward slash symbol (/). To divide one number by another, use this symbol. For example, to divide the value in cell A1 by the value in cell B1, the formula would be =A1/B1. You will see the result in the cell where you've put the formula. Division is great for calculating averages, percentages, or ratios. This formula is crucial for many financial, mathematical, and statistical calculations. From calculating percentages to determining profit margins, the ability to divide numbers accurately is essential for effective data analysis and decision-making. Are you ready for some more advanced concepts?

5. Using Cell References

Instead of typing the actual numbers into your formulas, you'll almost always use cell references. This means you use the cell's address (like A1, B2, C3) in your formula. The magic of cell references is that when you change the value in the referenced cell, the formula automatically updates. So, it's dynamic. This is one of the most powerful features of Excel. Cell references are the key to dynamic and flexible calculations. Cell references are essential for creating flexible and dynamic spreadsheets. If you want to change a value, you only have to change the cell value, and the final value is automatically changed.
