    Dispute at Home
    2(6)+ 7+8 over 3

    I think is solved as 2x6=12 then 7+8 =15 followed by 15 divided by 3 =5 and finally 12+5 =17
    Is this process correct?

    Depends on how the exact question is written

    2 X 6 equals 12
    12 plus 7 plus 8 equals 27
    27 over 3 will equal 9

    9 would be the final answer.


    ***you would be correct if it was written 2(6) +(7+8 over 3)

    Is it: 2(6)+ ((7+8)/3)

    Or:
    (2(6)+ 7+8)/3

    1 is 17 and 'tohter is 9
    So it is critical as to how the problem is posed.

    Following the rules for order of operations, the multiplication and division operators take precedent over addition and subtraction, so the answer is:
