tuskerval, Wrong. The answer is 100. You have to work left to right so this time subtraction comes first.

Why didn’t they put 60 as a wrong answer for those who mistakenly believe that addition comes before subtraction? I wish the writers would put some thought into the wrong answers.

Again, not a trivia question.
