Answer: 43
Explanation:
To solve the expression 9 - 8 + 6 × 7, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).
Here's the step-by-step solution:
1. First, perform the multiplication: 6 × 7 = 42.
2. Now, the expression becomes 9 - 8 + 42.
3. Next, perform the subtraction: 9 - 8 = 1.
4. Finally, perform the addition: 1 + 42 = 43.
So, the solution to the expression 9 - 8 + 6 × 7 is 43.
