Answer:
42 - 6 ÷ (6 - 3) = 40
Explanation:
BODMAS
The BODMAS rule is an acronym representing the order of operations in math:
- Brackets
- Orders (Powers and Square Roots, etc.)
- Division and Multiplication (from left to right)
- Addition and Subtraction (from left to right)
Given calculation:
42 - 6 ÷ 6 - 3 = 40
Following the order of operations, where division comes before subtraction, the current calculation is:
⇒ 42 - 6 ÷ 6 - 3
⇒ 42 - 1 - 3
⇒ 41 - 3
⇒ 38
Therefore, brackets should be added around (6 - 3) to make the calculation correct:
⇒ 42 - 6 ÷ (6 - 3)
⇒ 42 - 6 ÷ 3
⇒ 42 - 2
⇒ 40
