Question
### Instructions In each of the following, identify the computation that must be performed last. ### Problem a. \( 5 \cdot 6 - 3 \cdot 4 + 2 \) ### Solution Explanation 1. **Multiplication**: Perform \( 5 \cdot 6 \) and \( 3 \cdot 4 \) first due to the order of operations (PEMDAS/BODMAS). 2. **Subtraction**: Subtract the result of \( 3 \cdot 4 \) from the result of \( 5 \cdot 6 \). 3. **Addition**: Add 2 to the result of the subtraction. In this expression, the last computation to perform is the addition (adding 2).
