Answer 3

It seems like you're trying to add numbers, but the format you've provided is a bit unclear. If you could provide the numbers in a more standard way, I'd be happy to help you with the addition. For example:

513 + 20 + (-87) + 12 = ?

In this case, the sum would be calculated by adding all the numbers together. Let me know if this is what you intended or if you have a different format in mind.
