[quote="rookie1ja"]100 - Back to the Number Puzzles
Using four sevens (7) and a one (1) create the number 100. Except the five numerals you can use the usual mathematical operations +, -, x, :, root and brackets ().

The language should be changed in the problem. Drop the word "EXCEPT" and replace it with the phrase "In addition to".

By inverting 2 of the 4 - 7's

1 L7 L7

Ha Ha ! !



Very clever... Mind if I copy it?
