Let's Break Down This Equation: (67-18) ÷ 7 × 3
This equation involves a few different operations, so we need to follow the order of operations (PEMDAS/BODMAS) to get the correct answer.
PEMDAS/BODMAS stands for:
- Parentheses ( Brackets)
- Exponents ( Orders)
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Let's apply these rules to our equation:
- Parentheses/Brackets: First, we need to solve the operation inside the parentheses: 67 - 18 = 49
- Division: Next, we divide 49 by 7: 49 ÷ 7 = 7
- Multiplication: Finally, we multiply 7 by 3: 7 × 3 = 21
Therefore, the answer to the equation (67-18) ÷ 7 × 3 is 21.
