Differance between Expanded Notation vs. Standard Notation ?
A number written in expanded notation is broken down into parts just like it is in a place-value table.
Example: Write 574,789 in expanded notation.
500,000 + 70,000 + 4,000 + 700 + 80 + 9
You are probably used to seeing numbers written in standard notation, such as 574,789. To convert numbers in expanded notation back to standard notation, just add up all the numbers.
