Expanded notation is expanding the whole number by each place value.

Example: 1,234 = (1,000 * 1) + (100 * 200) + (10 * 3) + (1 * 4)
Expanded Notation is where you make a number sentence out of that number by looking at the hundreds, thousands, ect. For example I have the number 423 then this would be the expanded notation: 100 times 4 because the number 4 is in the hundreds place. The number 2 would be placed like this: 10 times 2 because the number 2 is in the tens place. And the number 3 would be placed like this: 3 times 1 because 3 is in the ones place. So the whole equation would look like this: 100 times 4 + 10 times 2 + 1 times 3 = 423
