Checked with my son the brain, and he agreed with me.  He has always been good in math and is now an accountant.

7 + ( 7 / 7 ) + ( 7 x 7 ) - 7 =  50

7   +      1       +     49   -  7   =  50

8            +     49   -   7   =  50

57          - 7        =   50

50 = 50

I respectfully disagree, the way it is written does not show any parenthesis that we would consider first, therefor it would be done in the order shown and the correct answer is 56. What does the rule say when there are no paranthesis? Where do we asssume they go. I have always sucked at math......
