What is a negative times a positive times a positive?

A negative. If you have a string of positive and negative numbers multiplied together, all you need to find the sign of the answer is to find the parity of the negative numbers. If there are an odd number of negatives then the answer is negative and if there are an even number of negatives then the answer is positive. Remember, positive numbers make no difference to the sign of the answer.


Why does every integer have an opposite?

The numbers 1,2,3,... etc are called natural numbers or counting numbers. Integers are the natural numbers plus zero plus the negative ( or opposite ) natural numbers. Why do we need negative natural numbers ? For one thing x + 1 = 0 is an equation whose solution is x = -1. We could not solve this equation if we did not have negative integers. So over history these negative numbers came about as a way to solve certain math problems. The numbers 1,2,3,... etc are called natural numbers or counting numbers.
