Math with integers

Question

Suppose that you randomly choose three of

these four integers: 8, 8, 18, and 28. Is

the sum likely to be positive, negative, or 0? and why?

Answer 1

Hello Lovely!

When you take out one number randomly one of the numbers from 8, 8, 18, and 28, you will get a positive number, as all four of the numbers in our list are positive. Then, if we pick three numbers, we will get three positive numbers.

Also, the sum of positive numbers will always be positive as well.

I'll leave it to you now to come up with a conclusion. Hope this helps with approaching the problem!
