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) x (7+7) = 112 would be a good attempt, but not
right, because it is not 100.
Solution:
Two solutions:
a) 177-77 = 100
b) (7+7) × (7+(1 ÷ 7)) = 100
(NO WINNER)
