Place Value

Back

The value of each digit in a number. In our number system, each place has a value 10 times more than the place value to the left. The first place is the ones, then the tens, then the hundreds. The places keep going for larger and larger numbers.

Front

Regroup

Back

Converting a place total greater than 10 to 1 of the next place, with the remainder staying in the current place. Or, converting one from a larger place to 10 of the next smaller place. Regrouping is done to keep each place less than 10 when adding, and to make it possible to subtract when the number being subtracted is larger than the other number.
