Order of Operations

• addition
  

• subtraction

• multiplication

• division

Answer explanation

In the expression 1 + 8 ÷ 2, division should be performed first according to the order of operations (PEMDAS/BODMAS). Therefore, the correct operation to perform first is division.

• multiplication
  

• subtraction

• division

Answer explanation

In the expression 4×6-3, multiplication should be performed first according to the order of operations (PEMDAS/BODMAS). Therefore, the correct operation to perform first is multiplication.

• addition

• multiplication

• parenthesis

• subtraction

Answer explanation

In the expression (2+5) - 4^2, you should perform the operation inside the parentheses first. This is because according to the order of operations (PEMDAS/BODMAS), parentheses take precedence over addition, multiplication, and subtraction.

• exponent

• parenthesis

• division

• subtraction

Answer explanation

In the expression 8^2 ÷ (8-4)^2, you should perform the operation inside the parentheses first, which is (8-4). This is because according to the order of operations, parentheses take precedence over other operations.

• exponent

• division

• addition
  

• subtraction

Answer explanation

In the expression -4 + 3^3 ÷ 5, the order of operations (PEMDAS/BODMAS) dictates that we perform exponents first. Therefore, the correct first operation is 'exponent', which is 3^3.

12 - 4 x 2 = 

• 16

• 4

• 8

• 18

Answer explanation

To solve 12 - 4 x 2, follow the order of operations: first multiply 4 by 2 to get 8, then subtract that from 12. So, 12 - 8 equals 4, making the correct answer 4.

18 + (6 – 2) × 2 =

(a)  

Answer explanation

First, solve the parentheses: 6 - 2 = 4. Then, multiply: 4 × 2 = 8. Finally, add: 18 + 8 = 26. Therefore, the correct answer is 26.

15 + 7 × 2 – 11 + 35=

• 38

• 251

• 53

• 50

Answer explanation

To solve 15 + 7 × 2 – 11 + 35, follow the order of operations: first, calculate 7 × 2 = 14. Then, 15 + 14 = 29. Next, 29 – 11 = 18, and finally, 18 + 35 = 53. Thus, the correct answer is 53.

(9 + 23) ÷ (5 - 3) = 

• 16

• 32

• 15

• 12

Answer explanation

To solve (9 + 23) ÷ (5 - 3), first calculate the expressions in parentheses: 9 + 23 = 32 and 5 - 3 = 2. Then divide: 32 ÷ 2 = 16. Thus, the correct answer is 16.
