Breaking Down Numbers into Expanded Form
Breaking down numbers into expanded form is a useful skill in mathematics, allowing us to understand the place value of each digit within a number. This concept is essential in various mathematical operations, including addition, subtraction, multiplication, and division.
Understanding Expanded Form
Expanded form is a way of expressing a number as the sum of its individual digits multiplied by their respective place values. For example, the number 456 can be written in expanded form as:
400 + 50 + 6
Where:
- 4 is the hundreds place
- 5 is the tens place
- 6 is the ones place
Breaking Down 612,300 in Expanded Form
Now, let's break down the number 612,300 into expanded form:
612,300 = 600,000 + 10,000 + 2,000 + 300
Where:
- 600,000 is the hundreds of thousands place
- 10,000 is the tens of thousands place
- 2,000 is the thousands place
- 300 is the hundreds place
We can further break down the number into:
612,300 = 600,000 + 10,000 + 2,000 + 300 + 0 tens + 0 ones
Where:
- 0 tens is the tens place
- 0 ones is the ones place
