What is the answer to this sum?
9 Answers
I've seen this sum 2 + 2(2+2) x 2 = ?
I would have thought the answer was 20, however Google says it is 18. What are the rules for when you add or multiply? Do you do all the multiplying first then add or what?

The trouble with BODMAS is that it is just a formula which you are encouraged to follow. But by the basic rules of arithmetic the problem given is ambiguous because the x2 is not attached.
What is the point of using 2(2+2) to signify doubling the contents of the brackets only to use a different method (x2) to multiply that content again?
Two possible answers are 18 or 20 depending on how you see the x2. The problem needs to be less sloppily expressed.
