Answer: -1,066
describe as a 7th grader in a semi-short sentance and still have some explaining on how its correct.

Answer 1

When you multiply 82 by -13, you get -1,066 because multiplying a positive number by a negative number always gives you a negative result, and if you do the regular multiplication of 82 and 13, you get 1,066, but since one of the numbers is negative, the final answer is -1,066.
