Would 3 negative numbers be a positive number?

3 negative numbers are three negative numbers. There are a lot of things you can do with them: -- You can add them up. Their sum is always a negative number. -- You can add two of them and subtract the third one from the sum. The result could be a positive number or it could be a negative number. It depends on the three negative numbers you started with. -- You can multiply them all together. The product is always a negative number. -- You can multiply all of their absolute values together. The product is always a positive number. -- You can multiply two of them, and divide the product by the third one. The result is always a negative number. -- You can multiply two of them, then raise the product to the power of the third one. The result is always a positive number. -- You can divide one of them by another one, then raise the quotient to the power of the third one. The result is always a positive number. But, as I said at the top, 3 negative numbers are never anything else other than three negative numbers.
