Answer: Yes you are correct. The answer is -30
Explanation:
We are adding 2 negatives. So we effectively add the positive versions of each number, and then make the result negative.
You can think of it in terms of money: you start off 27 dollars in debt and then borrow 3 more dollars to be a total of 27+3 = 30 dollars in debt.
Or you can think of it like you're under the ocean. Writing -27 could mean you're 27 feet below sea level. Adding on -3, ie subtracting 3, would then move you down 3 feet to get to 27+3 = 30 feet below sea level.
