Introduction

In mathematics, expanded form is a way of writing a number by breaking it down into its individual digits and their respective place values. This concept is essential in understanding and working with large numbers, and it has numerous applications in various fields, including finance, science, and engineering. In this article, we will explore the expanded form of a large number, specifically the number 7,080,267.

Understanding Place Values

Before we dive into the expanded form of 7,080,267, let's review the concept of place values. Place values refer to the position of a digit in a number, which determines its value. The place values for a number are as follows:

Millions: The digit in the millions place is multiplied by 1,000,000.
Hundred Thousands: The digit in the hundred thousands place is multiplied by 100,000.
Tens of Thousands: The digit in the tens of thousands place is multiplied by 10,000.
Thousands: The digit in the thousands place is multiplied by 1,000.
Hundreds: The digit in the hundreds place is multiplied by 100.
Tens: The digit in the tens place is multiplied by 10.
Ones: The digit in the ones place is multiplied by 1.

Expanded Form of 7,080,267

Now that we have a solid understanding of place values, let's break down the number 7,080,267 into its expanded form.

7,080,267 = 7 × 1,000,000 + 0 × 100,000 + 8 × 10,000 + 0 × 1,000 + 2 × 100 + 6 × 10 + 7 × 1

Calculating the Expanded Form

To calculate the expanded form of 7,080,267, we need to multiply each digit by its respective place value and add the results together.

7 × 1,000,000 = 7,000,000
0 × 100,000 = 0
8 × 10,000 = 80,000
0 × 1,000 = 0
2 × 100 = 200
6 × 10 = 60
7 × 1 = 7

Adding the Results Together

Now that we have the results of each multiplication, let's add them together to get the expanded form of 7,080,267.

7,000,000 + 0 + 80,000 + 0 + 200 + 60 + 7 = 7,080,267

Conclusion

In conclusion, the expanded form of 7,080,267 is 7,000,000 + 80,000 + 200 + 60 + 7. This concept is essential in understanding and working with large numbers, and it has numerous applications in various fields. By breaking down a number into its individual digits and their respective place values, we can gain a deeper understanding of its value and perform calculations with ease.
