Frequently Asked Questions
What is expanded form?
It writes a number as the sum of the value of each digit, so 123 becomes 100 + 20 + 3.
What happens to zeros?
Place values of zero are skipped, so 1080 becomes 1000 + 80 rather than including any zero terms.
Does it work for negative numbers?
Yes. The minus sign is kept in front of the expanded sum.
What is this useful for?
