I say that - |-15|-| 41|= -56; my best friend say that -| -15|- |41|= -26. Which one of us is correct? This answer depends on a dinner. Thanks.

- |-15|-| 41|

= -15 - 41
= -56

You win the dinner.
What do I get out of it ?

A great big thank you!!!

To determine who is correct, let's break down the given expression step by step and evaluate it.

The given expression is: - |-15| - |41|

Step 1: Evaluate the absolute values
The absolute value of -15 is 15, and the absolute value of 41 is 41.

Now, our expression becomes: - |15| - |41|

Step 2: Evaluate the remaining expression
The absolute value of 15 is 15, and the absolute value of 41 is 41.

Considering that all the absolute values have been evaluated, our expression becomes: -15 - 41.

Now, let's calculate the final result: -15 - 41 = -56.

Therefore, based on the evaluation, your claim that - |-15| - |41| = -56 is correct.

It's important to note that the correct answer was determined through the process of evaluating the expression step by step. By following this process, you can verify the correctness of mathematical expressions in the future.
