Answer 2

To solve this mathematical expression, 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).

Let's break down your expression step by step:

1. Start with the multiplication and division:

   • 8 * (-9) = -72

2. Now, rewrite the expression with the result of the multiplication: -28 / 7 + (-72) + 63

3. Continue with the division: -28 / 7 = -4

4. Now, rewrite the expression with the result of the division: -4 + (-72) + 63

5. Finally, perform addition and subtraction from left to right: -4 + (-72) = -76 -76 + 63 = -13

So, the answer to the expression -28/7 + 8*(-9) + 63 is -13.
