Question 982697: quantitative comparison
which is larger
Col A : -x*-y*-z
Col B: -x + -y + -z
My reasoning: not enough information to determine the larger. Both yield a negative result unless one of the variables = zero, resulting in col a being larger in that case.
Please let me know if I am correct and if my reasoning is correct. Thanks! :)

You can put this solution on YOUR website! .
Insufficient information, but your reasoning is flawed.
What if one or more variables are negative?
If all are negative, both are positive
What if they are between -1 and 1? (The sum is larger than the product if all are between 0 and 1, product larger if all between -1 and 0)
What about combinations of fractions, positive and negative?
There really not enough information as given to make any assumption.
