Writing a whole number in expanded form means expressing it as the sum of the values of its digits. Each digit is multiplied by its place value, and then all these products are added together.
For example, let’s take the number 346. In this number, the digit 3 is in the hundreds place, the digit 4 is in the tens place, and the digit 6 is in the ones place. To write it in expanded form, you would do the following:
- The digit 3 represents 300 (3 x 100).
- The digit 4 represents 40 (4 x 10).
- The digit 6 represents 6 (6 x 1).
Putting it all together, you would write:
300 + 40 + 6
This is the expanded form of the number 346.
In summary, to write a whole number in expanded form, identify each digit’s place value, calculate its value, and then sum these values to create an equation that represents the whole number.
