Writing three-digit numbers in expanded form
Expanded form writes a number as the sum of its place values. A three-digit number contains hundreds, tens, and ones. A zero digit means that place contributes zero to the sum.
A method you can use
- Read each digit with its place, not just its face value.
- Write the value of the hundreds, tens, and ones.
- Add the parts; a zero-value term may be included or omitted.
Worked examples
