Answer 2

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

1. Parentheses/Brackets
2. Exponents/Orders (e.g., squares and square roots)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's break down your expression step by step:

-2.5 * (-1.6) + 41.6 / (-4)

First, perform the multiplication and division:

-2.5 * (-1.6) = 4.0 (Remember that the product of two negative numbers is positive)

41.6 / (-4) = -10.4 (The division of a positive number by a negative number is negative)

Now, you have:

4.0 + (-10.4)

Finally, add the two results together:

4.0 + (-10.4) = -6.4

So, the result of the expression is -6.4.
