Answer:
72.
So I think either the question you have written here is incorrect or your missing brackets or operations
Explanation:
Applying BODMAS Rule
B- Bracket
O- Order
D- Division
M- Multiplication
A- Addition
S- Subtraction
we get to know the order in which each of the operations should be performed
Step 1 :- Division i.e, 15÷5
So we get 52 + 3 . 6 + 2
Step 2 :- Multiplication I.e, 3.6
So we get 52 + 18 + 2
Step 3 is direct addition
So the answer is 72
