Order of Operations

Solve 1

100

3 + 6 x 4

27

3 + 6 x 4 = 27

200

25 ÷ 5 - 2

3

25 ÷ 5 - 2 = 3

300

12 - 8 ÷ 2 + 3

11

12 - 8 ÷ 2 + 3 = 11

400

20 ÷ (8 - 3) + 16

20

20 ÷ (8 - 3) + 16 = 20

500

7 + 3 x (8 ÷ 4)

13

7 + 3 x (8 ÷ 4) = 13

Solve 2

100

(6 - 2) x (5 - 1)

16

(6 - 2) x (5 - 1) = 16

200

(15 - 5) x 10  + 3

103

(15 - 5) x 10  + 3 = 103

300

6 x 8 + (7 - 6)

49

6 x 8 + (7 - 6) = 49

400

(19 - 5) + 20

34

(19 - 5) + 20 = 34

500

2 x (3 x 5) + 6

36

2 x (3 x 5) + 6 = 36

Fix My Mistake

100

9 - 3 x 2 = 12

9 - 3 x 2 = 3

200

10 ÷ 5 x 2 = 1

10 ÷ 5 x 2 = 4 

300

5 x 5 + 1 = 30

5 x 5 + 1= 26

400

4 + 5 + 7 - 3 x 2 = 26

4 + 5 + 7 - 3 x 2 = 10

500

The problem was 20 - 5 x 2 + 3. 

My answer was 33. 

What did I do wrong?

I did not multiply first. 

The answer should be 13.

20 - 5 x 2 + 3 = 13

What number is missing?

100

4 x 3 + ? = 18

6

4 x 3 + 6 = 18

200

10 - 3 x ? = 4

2

10 - 3 x 2 = 4

300

? + 2 x 5 = 30

20

20 + 2 x 5 = 30

400

6 x (5 - ?) = 18

2

6 x (5 - 2) = 18

500

(25 - ?) ÷ 3 = 5

10

(25 - 10) ÷ 3 = 5

What operation is missing?

100

5 ? 3 - 1 = 7

+

5 + 3 - 1 = 7

200

50 + 4 ? 5 = 70

x

50 + 4 x 5 = 70

300

6 x 3 ? 4 = 14

-

6 x 3 - 4 = 14

400

(10 ? 8) x 3 = 6

-

(10 - 8) x 3 = 6

500

10 - 16 ? 4 = 6
