Expanded form definition

Answer 1

[AI-generated answer — Bot GPT 3.5]

Expanded form, also known as expanded notation, is a way of representing a number by breaking it down into its individual place values. In expanded form, each digit is written separately, followed by its corresponding place value. The place values are determined by the position of the digit in the number, such as ones, tens, hundreds, thousands, etc.

For example, the number 345 in expanded form is written as 300 + 40 + 5, or as 3 hundreds, 4 tens, and 5 ones. This breakdown makes it easier to understand the value of each digit and the overall value of the number.

Expanded form is commonly used in teaching and learning place value concepts, particularly in elementary mathematics. It helps emphasize the importance of understanding the significance of each digit's position in a number and reinforces the concept of place value.
