No. They are unsigned, therefore all representations are positive.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
It can. Negative 2 minus negative 1 = negative 1. However, it sometimes might be positive. Negative 5 minus negative 16 = positive 11. If you have two equal negative variables, such as -a - -a, you will get -2a. -2a may still be positive though, if a is a negative number. An example of having two unequal negative numbers is -a - -b, which is -a + b. That may be positive or negative depending on what a and b are equal to.
Negatives and Positives Positive + Positive = Positive Negative + Negative = Positive Negative + Positive = Negative Positive + Negative = Negative
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.
it is negative. negative/negative = positive. negative/positive = negative
positive and a positive is a positive negative and a negative is a positive to answer your question: positive and a negative is a negative.
