Fact: If a and b are non-negative numbers, then ab is non-negative.
What is the equivalent contrapositive statement of the above?
I think it is:
If ab<0, then at least one of a and b <0.
Am I right?
But this implication doesn't seem quite right to me...shouldn't the correct statement be...
If ab<0, then exactly one of a and b <0 ?
Could someone please explain?
Thank you!
