Sounds like a trick question, since standard form is converted into expanded notation and vice versa. 

Even 1 is written as 1 * 10^0.

LOL - my wife gave that same example.

Sorry about the question. I didn't post my answer. Anyhow, here it is:

100 = 100 + 0 + 0
200 = 200 + 0 + 0

Is this correct????

I think I've been over-analyzing this simple math problem for my son's homework.

Simple 3rd grade math problem:

How many numbers from 1 to 200 have an expanded form that is identical to the standard form? What are they?
