Question

Give an example of three numbers the fit the description below:

- the sum of the numbers is positive and the product is negative

Answer 1

Ok so with 3 numbers there are 2 ways to get a negative product.

1. - * - * - = -

Or

2. + * + * - = -


Since we know the sum is going to be positive, we are going to use the 2nd example.


So we need to find 3 numbers that the 2 positives together are greater than the negative.

Answer 2

So, just for an extreme example,

1000 + 1000 + (-1) are 3 numbers that have a positive sum. (1999)

Answer 3

But have a product,

1000 * 1000 * (-1) = -1,000,000

Answer 4

That is negative. So that being said, can you now find two more examples that multiply into negative but add into positive?

Answer 5

-1+2+3=4
product
-1*2*3=-6
think of more

Answer 6

Thanks a lot guys, I appreciate it! :)
