Four sevens and one one. (Posted on 2010-09-06) Difficulty: 1 of 5
Using four sevens (7,7,7,7) and a one (1) create the number 100.
You can use not more than three out of the usual mathematical operations (+, -, x, /, sqrt and power) and any amount of brackets.

Are we allowed to use a decimal point in creating out numbers? If so, would we also have to acknowledge leading zeros? For example, would .1 be a valid value to use in our calculations, or would that be considered 0.1 and invalid in our case?
