Find the answer that shows the correct Order of Operation and the correct answer.
83 - 19 + (31 + 17) ÷ 6 =
83 - 19 + (31 + 17) ÷ 6 =
31 + 17 = 48
48 ÷ 6 = 8
83 - 19 = 64
64 + 8 = 72
48 ÷ 6 = 8
83 - 19 = 64
64 + 8 = 72
83 - 19 = 64
31 + 17= 48
48 ÷ 6 = 8
64 + 8 = 72
31 + 17= 48
48 ÷ 6 = 8
64 + 8 = 72
31 + 17 = 48
83 - 19 = 64
64 + 48 = 112
112 ÷ 6 = 18.67
83 - 19 = 64
64 + 48 = 112
112 ÷ 6 = 18.67
31 + 17 = 48
48 + 83 = 131
131 + 19 = 150
150 ÷ 6 = 25
48 + 83 = 131
131 + 19 = 150
150 ÷ 6 = 25
The Order of Operation requires us to work the math within parentheses first. Therefore, the first part would need to be 31 + 17 = 48. This shows us that Answer (b) is not correct. As we have no exponents we move on to multiplication and division, working left to right. As we have a division the next step is 48 ÷ 6 = 8. Next we work left to right giving us 83 - 19 = 64 and then 64 + 8 = 72. Answer (a) shows the correct Order of Operation

(5 + 7) x (4 + 8) - (9 x 2) - (6 x 6) =
(5 + 7) x (4 + 8) - (9 x 2) - (6 x 6) =
5 + 7 = 12
4 + 8 = 12
12 x 12 = 144
9 x 2 = 18
144 - 18 = 126
6 x 6 = 36
126 - 36 = 90
4 + 8 = 12
12 x 12 = 144
9 x 2 = 18
144 - 18 = 126
6 x 6 = 36
126 - 36 = 90
5 + 7 = 12
12 x 4 = 48
48 + 8 = 56
56 - 9 = 47
47 x 2 = 94
94 - 6 = 88
88 x 6 = 528
12 x 4 = 48
48 + 8 = 56
56 - 9 = 47
47 x 2 = 94
94 - 6 = 88
88 x 6 = 528
5 + 4 = 9
7 + 8 = 15
9 x 15 = 135
9 x 6 = 54
2 x 6 = 12
54 - 12 = 42
135 - 42 = 93
7 + 8 = 15
9 x 15 = 135
9 x 6 = 54
2 x 6 = 12
54 - 12 = 42
135 - 42 = 93
5 + 7 = 12
4 + 8 = 12
9 x 2 = 18
6 x 6 = 36
12 x 12 = 144
144 - 18 = 126
126 - 36 = 90
4 + 8 = 12
9 x 2 = 18
6 x 6 = 36
12 x 12 = 144
144 - 18 = 126
126 - 36 = 90
The Order of Operation requires us to work the math within parentheses first. Therefore, the first part would need to be 5 + 7 = 12, then 4 + 8 = 12, followed by 9 x 2 = 18 and finally 6 x 6 = 36. As there are no exponents we move on to multiplication and division. Working left to right we get 12 x 12 = 144. Next we do addition and subtraction so we then have 144 - 18 = 126 and then 126 - 36 = 90. Answer (d) shows the correct Order of Operation

Find the answer that shows the correct Order of Operation and the correct answer.
12 + 45 + (9 x 13) - 4 + (6 x 3) =
12 + 45 + (9 x 13) - 4 + (6 x 3) =
12 + 45 = 57
9 x 13 = 117 - 4 = 113
6 x 3 = 18
57 + 113 + 18 = 188
9 x 13 = 117 - 4 = 113
6 x 3 = 18
57 + 113 + 18 = 188
9 x 13 = 117
6 x 3 = 18
12 + 45 + 117 - 4 + 18 = 188
6 x 3 = 18
12 + 45 + 117 - 4 + 18 = 188
9 x 13 = 117
4 + 18 = 22
12 + 45 = 57
57 + 117 - 22 = 152
4 + 18 = 22
12 + 45 = 57
57 + 117 - 22 = 152
9 x 13 = 117
6 x 3 = 18
117 + 18 = 135
12 + 45 = 57
57 + 117 + 18 - 4 = 188
6 x 3 = 18
117 + 18 = 135
12 + 45 = 57
57 + 117 + 18 - 4 = 188
The answers given in (a), (b), and (d) are all the same and 188 is the correct final answer. Therefore, Answer (c) is not correct. As the Order of Operation requires us to work the math within parentheses first, the first part would need to be 9 x 13 = 117. We have a second set of numbers in parentheses so that goes next, i.e., 6 x 3 = 18. The next step in the Order of Operation is to do numbers with exponents, as we do not have any we move on to multiplication and division. As there are no multiplication and divisions to be done, we next do additions and subtractions working from left to right. So next we would have 12 + 45 + 117 - 4 + 18 = 188. Answer (b) shows the correct Order of Operation

43 - 20 = 23
7 x 4 = 28
23 + 28 = 51
21 ÷ 3 = 7
5 x 7 = 35
51 + 35 = 86
7 x 4 = 28
23 + 28 = 51
21 ÷ 3 = 7
5 x 7 = 35
51 + 35 = 86
43 - 20 = 23
21 ÷ 3 = 7
7 x 4 = 28
5 x 7 = 35
28 + 23 + 35 = 86
21 ÷ 3 = 7
7 x 4 = 28
5 x 7 = 35
28 + 23 + 35 = 86
Each answer shows the final answer as 86 and this is the correct answer. However, the Order of Operation must be followed making the first step to work the math within the parentheses. That would be 43 - 20 = 23 and 21 ÷ 3 = 7. The next step is to do numbers with exponents. As we do not have any, we move on to multiplication and divisions. Going from left to right, the next step will be 7 x 4 = 28. Next we have 5 x 7 = 35. Our final step is adding and/or subtracting. In this problem, working left to right, we will have 28 + 23 + 35 = 86. Answer (d) shows the correct Order of Operation
