A positive number multiplied by a positive number will give a positive answer:1 x 1 = 1In contrast, a negative number multiplied by a positive number gives a negative answer:-1 x 1 = -1Finally two negative numbers multiplied together give a positive answer:-1 x -1 = 1
27 multiplied by any negative number will give a negative product of 27.
Obviously, the answer is a composite number. Reason:A number multiplied by another number (besides 1) will give a result of a composite number. If a number is multiplied by 0, the answer will be 0 (which is not a prime number nor composite) unless a number has been added or subtracted to give either a negative or positive number, respectively.
A negative multiplied by another negative will always give a positive answer. E.g. -4 x - 3 = 12
