using bedmas rule since d is first , the left side number should be divisible by the right side number (8,2) which gives 4 (3,4,5,8)now multiplication should happen and also to maximise the value we would multiply 4 and 5 so we get 20 to which 3 is added and we get 23 from which 8 is substracted which gives 15 which satisfies the condition of getting maximum number without getting a fraction and a negative number
