Solving (67-18) ÷ 7 × 3 with PEMDAS
The order of operations, often remembered by the acronym PEMDAS, helps us solve mathematical expressions with multiple operations in a consistent way. PEMDAS stands for:
- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Let's break down the solution to (67-18) ÷ 7 × 3 using PEMDAS:
- Parentheses: First, we solve the expression within the parentheses: 67 - 18 = 49.
- Division: Next, we perform the division: 49 ÷ 7 = 7.
- Multiplication: Finally, we multiply: 7 × 3 = 21.
Therefore, the solution to (67-18) ÷ 7 × 3 is 21.
