Can multiplication and division operations be performed in either order?
A.
No
B.
Yes
C.
Sometimes
Correct Answer B. Yes
Explanation Multiplication and division operations can be performed in either order. This is because multiplication and division have the same precedence level and are left associative. Therefore, they can be performed from left to right in the order they appear in an expression. For example, in the expression 4 * 2 / 2, we can either perform the multiplication first (4 * 2 = 8) and then the division (8 / 2 = 4) or perform the division first (2 / 2 = 1) and then the multiplication (4 * 1 = 4). Both ways yield the same result, indicating that the order of operations can be interchanged.

Which expression correctly follows the BODMAS/BEDMAS rule?
A.
3 + (6 × 2) ÷ 3 - 4
B.
3 + 6 × (2 ÷ 3 - 4)
C.
3 + 6 × 2 ÷ 3 - 4
D.
3 + (6 ÷ 2) × 3 - 4
Correct Answer B. 3 + 6 × (2 ÷ 3 - 4)
Explanation B) 3 + 6 × (2 ÷ 3 - 4)
According to the BODMAS/BEDMAS rule, you should perform operations in the following order:
1. Brackets (or parentheses)
2. Orders (exponents and roots)
3. Division and Multiplication (from left to right)
4. Addition and Subtraction (from left to right)
In Option B:
1. Inside the brackets, you have the expression 2 ÷ 3 - 4.
2. Following the order, you should first perform the division and then the subtraction within the brackets:
- 2 ÷ 3 = 2/3 (which is approximately 0.67 when rounded to two decimal places)
- Then, 0.67 - 4 = -3.33 (rounded to two decimal places)
3. Now, you have 6 × (-3.33), which is equal to -19.98 (rounded to two decimal places).
4. Finally, you add 3 + (-19.98) to get -16.98 (rounded to two decimal places).
So, Option B correctly follows the BODMAS/BEDMAS rule by performing operations within the brackets first, then moving to the remaining operations in the specified order.
