as per the BODMAS firstly we solve brackets then division then multiplication then addition then subtraction. in this question brackets are not ,so we will solve firstly devision so A.T.Q.

90÷3=30×5-3+9

30×5=150-3+9

in the above I will have say that first we will solve addition then subtraction so firstly we will solve addition so ,

150+9=159

then we will solve subtraction so ,

159-3=156

so answer is = 156
