This question is just BIDMAS or PEDMAS or whatever abbreviation you use. I use BIDMAS, which is Brackets Indices Division Multiplication Addition Subtraction.
So first we need to find the brackets and do that first. However, we have a divide in the brackets so we have to do that before the addition in the brackets.
(15/5) + 6 + 9 is the order you should do the brackets.
So 3 + 6 + 9, which is 18. Now we have the brackets, we can now do the multiplication.
18 x 4 x 2 = 144
144 + 7 = 151
Therefore, your answer is 151.
Hope I helped!
