In a whole number, the digit farthest to the right is always in the ones place. The next farthest to the right is in the tens place. The remaining digits continue to fill in the place values until there are no digits left.

The number $\blueD4\greenD5\goldD9$start color #11accd, 4, end color #11accd, start color #1fab54, 5, end color #1fab54, start color #e07d10, 9, end color #e07d10 is made up of $\blueD4$start color #11accd, 4, end color #11accd hundreds, $\greenD5$start color #1fab54, 5, end color #1fab54 tens, and $\goldD9$start color #e07d10, 9, end color #e07d10 ones.

We can also write this as: $\blueD4\greenD5\goldD9=\blueD{400}+\greenD{50}+\goldD9$start color #11accd, 4, end color #11accd, start color #1fab54, 5, end color #1fab54, start color #e07d10, 9, end color #e07d10, equals, start color #11accd, 400, end color #11accd, plus, start color #1fab54, 50, end color #1fab54, plus, start color #e07d10, 9, end color #e07d10.
