A NUMBER WRITTEN AS THE SUM OF THE VALUE OF ITS DIGITS.

Remember when we looked at numbers and their value?

thousands hundreds tens ones

2, 3 7 5

The value of the 2 is 2 thousands, or 2,000

The value of the 3 is 3 hundreds, or 300

The value of the 7 is 7 tens, or 70

The value of the 5 is 5 ones, or 5
