The Puzzle: Using the numerals 1,7,7,7 and 7 (a "1" and four "7"s) create the number 100.
As well as the five numerals you can use the usual mathematical operations (+, -, x, ÷ and brackets ().
For example: (7+1) × (7+7) = 112 would be a good attempt, but not right, because it is not 100.
Example 71+7+7+7=92
Example 7*7=49*1=50+ (7*7)=99
