In math problems without punctuation such as brackets, the standard convention in to solve from left to right. Therefore, you would solve the problem 15-3 times 4 plus nine like by three actions. 15-3 equals 12; 12 times 4 equals 48; 48 plus 9 equals 57.
87 + 15 + 48 = 150
48 + 1 = 49
48 + 67 + 134 + 121 + 15 = 385
