Place value is the value of a digit in a number, based on its position in the number. For example, in the number 438, the 8 has a place value of 8 and the 3 has a place value of 300. Rounding is the process of estimating a number to a specific place value. Rounding is used to simplify large numbers and make calculations easier. Regrouping is a way of breaking down a number into more manageable parts. In regrouping, different place values, such as tens and ones, are combined to make larger place values, such as hundreds.
