Use the digits from 0 through 9
Can you use the digits from 0 through 9  using any of the four operations, addition, subtraction, multiplication and division  so that when you do the math you get 100? Each number can be used only once, but you can use them in any order that you like.

Use the digits from 0 through 9
Is there a formula for calculating the number of digits in a large number?
An example would be 218477
