Christmas Maths Challenge

Here is a problem which might require a little perseverance.  There is more than one solution.

Make a Century

By putting arithmetical signs (+ , - , x ) in suitable places between the digits make the following sum correct:

1   2   3   4   5   6   7   8   9  =  100

Note: The digits must remain in counting order but the spaces may be removed to make two or three digit numbers.  For example, the space between the 2 and 3 can be eliminated to make 23.  Brackets may be used if necessary.

Bring your solution(s) to Mrs. Hopkins by Thursday January 8th. The person who can find the most solutions will be able to have an extra session helping in Nursery (during lesson time).
