Introduction

Expanded notation is a mathematical technique used to represent numbers in a more detailed and explicit form. It involves breaking down a number into its place values, making it easier to perform calculations and understand the concept of place value. In this article, we will explore the concept of expanded notation and learn how to perform addition using this technique.

What is Expanded Notation?

Expanded notation is a way of representing numbers by breaking them down into their place values. Each place value is represented by a digit multiplied by a power of 10. For example, the number 456 can be represented in expanded notation as:

456 = 400 + 50 + 6

This can be further broken down into:

456 = 4 × 100 + 5 × 10 + 6 × 1

The Expanded Form of 64

To perform the addition using expanded notation, we need to first find the expanded form of 64. The expanded form of 64 is:

64 = 60 + 4

This can be further broken down into:

64 = 6 × 10 + 4 × 1

The Expanded Form of 79

Next, we need to find the expanded form of 79. The expanded form of 79 is:

79 = 70 + 9

This can be further broken down into:

79 = 7 × 10 + 9 × 1

Performing Addition Using Expanded Notation

Now that we have the expanded forms of 64 and 79, we can perform the addition using expanded notation. We will add the corresponding place values of the two numbers.

Step 1: Adding the Hundreds Place

The hundreds place of 64 is 60, and the hundreds place of 79 is 70. We will add these two numbers:

60 + 70 = 130

Step 2: Adding the Tens Place

The tens place of 64 is 0, and the tens place of 79 is 10. We will add these two numbers:

0 + 10 = 10

Step 3: Adding the Ones Place

The ones place of 64 is 4, and the ones place of 79 is 9. We will add these two numbers:

4 + 9 = 13

Step 4: Combining the Results

Now that we have added the corresponding place values, we can combine the results to get the final answer.

The hundreds place is 130, the tens place is 10, and the ones place is 13. Therefore, the final answer is:

143

Conclusion

In this article, we learned how to perform addition using expanded notation. We first found the expanded forms of 64 and 79, and then added the corresponding place values to get the final answer. This technique is useful for understanding the concept of place value and for performing calculations involving large numbers.
