Answer 3

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's calculate the expression step by step:

1. Start with the parentheses: 9.91 * (-98.7) = -978.417

2. Now, the second part of the expression: -98.7 * 9.9 = -978.03

3. Finally, subtract the two results: -978.417 - (-978.03) = -0.387

The final result of the expression is approximately -0.387.
