Solved Questions on BODMAS Rule
1. Simplify: 3 + 4 × 2
a) 11
b) 12
c) 14
d) 15
Answer: a) 11
Explanation: Using BODMAS, we perform multiplication before addition.
So, we first multiply 4 and 2, and then add 3 to the result: 3 + 4 × 2 = 3 + 8 = 11
2. Simplify: 8 + 3 × (6 - 2) ÷ 22
a) 4
b) 6
c) 11
d) 8
Answer: c) 11
Explanation:
First, evaluate inside the brackets: (6 - 2) = 4
Then, calculate the exponentiation: 22 = 4
Next, perform multiplication and division from left to right: 3 × 4 ÷ 4 = 12 ÷ 4 = 3
Finally, add to the initial 8: 8 + 3 = 11
3. Simplify: 5 + 3 × 4 – 2
a) 15
b) 16
c) 24
d) 30
Answer: a) 15
Explanation: Using BODMAS, we first perform multiplication, then addition, and finally subtraction.
So, we multiply 3 and 4 to get 12, then add 5 to get 17, and finally subtract 2 to get the final answer: 5 + 3 × 4 - 2
= 5 + 12 - 2
= 17 - 2
= 15
4. Simplify: 10 ÷ (5 - 3) + 2 × 3
a) 5
b) 6
c) 7
d) 11
Answer: d) 11
Explanation: Using BODMAS, we first perform the operations inside the parentheses, which is subtraction in this case.
So, 5 - 3 = 2.
Then, we divide 10 by 2 to get 5.
Finally, we multiply 2 by 3 to get 6, and then add it to 5 to get the final answer: 10 ÷ (5 - 3) + 2 × 3 = 10 ÷ 2 + 6 = 5 + 6 = 11
5. Simplify: (5 - 3) x (8 + 4) ÷ 6
a) 2
b) 3
c) 4
d) 6
Answer: c) 4
Explanation: Using the BODMAS rule, we first perform the operations inside the brackets: 5 - 3 = 2 and 8 + 4 = 12.
Then we perform the divide operation: 12 ÷6 = 2.
Finally, we perform the multiplication operation: 2 x 2 = 4.
Therefore, the simplified expression is 4.
