Answer : D

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right

,p>18 ÷ 3 + 3 × 3 – 8 = 6 + 9 – 8

Step 2:

We do all addition and subtraction from left to right

6 + 9 – 8 = 15 – 8 = 7

Step 3:

So 18 ÷ 3 + 3 × 3 – 8 = 7

Answer : B

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

28 ÷ 7 + 6 × 5 – 14 = 4 + 30 – 14

Step 2:

We do all addition and subtraction from left to right

4 + 30 – 14 = 34 – 14 = 20

Step 3:

So 28 ÷ 7 + 6 × 5 – 14 = 20

Answer : A

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

,p>17 × 3 – 42 ÷ 14 – 18 = 51 – 3 – 18

Step 2:

We do all addition and subtraction from left to right

51 – 3 – 18 = 51 – 21 = 30

Step 3:

So 17 × 3 – 42 ÷ 14 – 18 = 30

Answer : C

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

8 – 12 ÷ 4 + 5 × 3 = 8 – 3 + 15

Step 2:

We do all addition and subtraction from left to right

8 – 3 + 15 = 5 + 15 = 20

Step 3:

So 8 – 12 ÷ 4 + 5 × 3 = 20

Answer : B

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

20 – 18 ÷ 6 + 9 × 2 = 20 – 3 + 18

Step 2:

We do all addition and subtraction from left to right

20 – 3 + 18 = 17 + 18 = 35

Step 3:

So 20 – 18 ÷ 6 + 9 × 2 = 35

Answer : D

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

8 + 4 × 6 – 8 ÷ 2 = 8 + 24 – 4

Step 2:

We do all addition and subtraction from left to right

8 + 24 – 4 = 28

Step 3:

So 8 + 4 × 6 – 8 ÷ 2 = 28

Answer : C

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

7 – 52 ÷ 13 + 6 × 5 = 7 – 4 + 30

Step 2:

We do all addition and subtraction from left to right

7 – 4 + 30 = 3 + 30 = 33

Step 3:

So 7 – 52 ÷ 13 + 6 × 5 = 33

Answer : A

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

28 ÷ 7 + 2 × 4 – 10 = 4 + 8 – 10

Step 2:

We do all addition and subtraction from left to right

4 + 8 – 10 = 12 – 10 = 2

Step 3:

So 28 ÷ 7 + 2 × 4 – 10 = 2

Answer : A

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

15 – 6 ÷ 2 + 4 × 4 = 15 – 3 + 16

Step 2:

We do all addition and subtraction from left to right

15 – 3 + 16 = 12 + 16 = 28

Step 3:

So 15 – 6 ÷ 2 + 4 × 4 = 28

Answer : D

Explanation

Step 1:

We follow PEMDAS rule in simplifying this expression.

We do multiplication and division from left to right.

18 ÷ 6 + 3 × 7 – 11 = 3 + 21 – 11

Step 2:
