Order of Operations | MCQs

Explanation

3+4*(7+1)=?

3+4*8=3+32

=35

Explanation

Step 1: Follow the order of operations (PEMDAS/BODMAS)

First, calculate 6 × 4 × 0.5

Step 2: Calculate 6 × 4

6 × 4 = 24

Step 3: Multiply 24 by 0.5

24 × 0.5 = 12

Step 4: Add 2 to the result

2 + 12 = 14

Explanation

According to BODMAS, brackets are solved first. So, the expression inside the brackets 

(3+2) will be solved first before proceeding with multiplication or addition.

Explanation

To evaluate this expression, we need to follow the order of operations (PEMDAS):

• Divide 28 by 7: 28 ÷ 7 = 4
• Multiply 4 by 2: 4 × 2 = 8
• Add 9 to 8: 9 + 8 = 17

So, the correct answer is: 17

Explanation

(4+3) × (8-2) = ?

= 7 x 6 

= 42

Explanation

2 is the correct answer.

Explanation

To evaluate the expression:

1. Squaring: 4² = 16

2. Subtracting: 3 - 16 = -13

3. Adding: -13 + 62 = 49

Explanation

1. Perform the multiplication:

$$9\times 10=90$$

2. Divide the result by 45:

$$90÷45=2$$

Explanation

• To solve (124/2) × 2:
• First, calculate 124/2 = 62.
• Then, multiply 62 by 2:
• 62 × 2 = 124
• So, the answer is 124.

Explanation

• To solve 3 x (6 + 3):
• First, we calculate 6 + 3 = 9
• Then, multiply 3 by 9:
• 3 x 9 = 27
