# If you add a positive and a negative number how can you tell whether the answer will be positive negative or equal?

If the negative number is bigger then the answer will be negative If the bigger number is positive then the answer will be positive. All you do is subtract the two numbers and take the sign of the bigger number Ex (+2)+(-7)=(-5)

Positive. A negative number added to a positive would reduce the original to a smaller positive, to zero, or to a negative depending on their relative values but subtracting a negative number from a positive number will always increase the value of the positive.
