Hi.
102+6(7)+8 (your equation)
102+ 42+ 8 (since the order is PEMDAS, multiplication has to go first. 6x7=42
144 + 8 (since you go left to right, 102 +42 has to be 1st. Answer= 144)
152 (now the only thing left is 144 + 8, so do that. Answer= 152.)
Since that's the last step, 152 will be your answer.
