11 + 5 + 3 X 2 + 8 X 1

BIDMAS tells us the order of how we should solve each answer. It stands for:
B(rackets) I(ndices) D(ivision) M(ultiplication) A(ddition) S(ubtraction) 

By using BIDMAS, we know that the multiplication steps should be done first:
11 + 5 + (3 X 2) + (8 X 1)

Now we can more onto the addition:
11 + 5 + 6 + 8
11 + 5 + 6 + 8 = 30

11 + 5 + 3 x 2 + 8 x 1 = 30
