Multiplication is a basic math operation, related to addition. It is the process of finding the accumulated product of the quanity of one number added to itself the amount of times of the other number. The multiplication of two positive integers could be represented by elements in two sets. When each element in the first set is replaced with the number of elements contained in the second set then the total number of elements produced is the multiplied product. Multiplication of positive numbers on a number line can be shown graphically by concatenating the length of one line to itself the number of times represented by the other number. The multiplication sign designates this operation in equations. The operation of multiplication works within the boundaries of the set of all real numbers, as well as the set of imaginary numbers. The multiplication of a negative number times a positive number yields a negative result, but two negatives make a positive. In the multiplication of common fractions the numerator is multiplied times the numerator and the denominator times the denominator. Other math functions use multiplication in their equations. Multiplication has the commutative property, so the two numbers multiplied are interchangeable.

12 x 3 = 36,
5 x 19 = 95,
2 x (-8) = -16,
(-6) x (-8) = 48.
Multiplication of fractions:
2/3 x 3/4 = 6/12 = 1/2,
5/7 x 2/3 = 10/21.
