is says Simplify the expression thats all it says
OpenStudy (rina.r):
but a point and a bracket can change teh answer so all i am saying is that is it a bracket after 4 or point?
OpenStudy (anonymous):

57 – 12 ÷ 4 x 3
57-12/ 12
1
57-1
so 56 is the right answer.

12 divide by 12 gives u 1 an dthen u subtract from 57 gives u 56 by using BIMDAS rule.
