Absolutely not!
The real numbers are partitioned into three sets: {negatives}, {0}, & {positives}.
You are confusing two concepts.
So authors insist that 0 is a counting number.
Some say no it is a whole number but not a natural number.
Others disagree with both of those.
But that has nothing to do with 0 being positive. It is not.
Hi, NeedHelp18!
All positive real numbers have two real square roots. However, the radical notation generally refers only to the principal square root, which is always the nonnegative value. If you want to represent both square roots, use the notation . This also applies to . As others mentioned, things get more complicated when you bring complex values into consideration.
And no, Moo, 0 is neither positive nor negative, but it may be included in the set of natural numbers depending on what definition you are using.
