Rumus Operasi Dasar Matematika di Excel

Introduction

This tutorial will guide you through the basic mathematical operations in Excel. You will learn how to create formulas for addition, subtraction, multiplication, division, square roots, and exponentiation. Understanding these operations is essential for anyone looking to perform calculations efficiently in Excel.

Step 1: Creating a Simple Addition Formula

To begin with, let’s learn how to perform addition in Excel.

1. Open Excel and select a cell where you want the result to appear.
2. Type = to indicate you are entering a formula.
3. Enter the first number, then use the + operator, followed by the second number. For example:

   =5 + 10
   

4. Press Enter to see the result.

Practical Tip

: You can also add the values of other cells. For example:

=A1 + B1

Step 2: Performing Subtraction

Next, let’s move on to subtraction.

1. Select a cell for your result.
2. Type = followed by the first number, then - and the second number. For instance:

   =20 - 5
   

3. Press Enter to calculate.

Practical Tip

: Subtraction can also refer to cell references:

=C1 - D1

Step 3: Multiplying Numbers

Now, let’s learn how to multiply numbers using Excel.

1. Click on the cell where you want the result.
2. Type = followed by the first number, then * (the multiplication operator), and the second number. For example:

   =4 * 6
   

3. Press Enter to see the product.

Common Pitfall

: Ensure you use the asterisk * for multiplication instead of the letter x.

Step 4: Dividing Numbers

Next, you will learn how to divide numbers in Excel.

1. Select a cell for the result.
2. Type = followed by the dividend, then / (the division operator), and the divisor. For example:

   =15 / 3
   

3. Press Enter to perform the division.

Practical Tip

: You can divide the values of cells:

=B2 / C2

Step 5: Calculating Square Roots

To find the square root of a number, use the SQRT function.

1. Click on a cell for your result.
2. Type =SQRT( followed by the number or cell reference. For example:

   =SQRT(16)
   

3. Close the parenthesis and press Enter.

Step 6: Using Exponents

For exponentiation, use the caret ^ operator.

1. Choose a cell for displaying your result.
2. Type = followed by the base number, then ^, and the exponent. For example:

   =2 ^ 3
   

3. Press Enter to calculate.

Practical Tip

: You can also use cell references:

=A1 ^ B1

Conclusion

In this tutorial, you have learned how to perform basic mathematical operations in Excel, including addition, subtraction, multiplication, division, square roots, and exponentiation. These operations form the foundation for more complex calculations in Excel. Explore these functions further to enhance your skills, and consider experimenting with more advanced formulas as you become comfortable with these basics.
