Factor times factor equals product is multiplication. The simple operation of finding the sum of several identical addends is called multiplication. The two numbers multiplied together are called factors, and the resulting number is called the product. In mathematics, the relationship between the factors of x and the product is called the relationship between the parts of multiplication. They are: product = factor x factor. Factor = product of another factor. Of course, division is the inverse of multiplication. In division, the known product is called the dividend, and the divisor and the quotient are two factors.

The operation laws of multiplication

The operation laws of multiplication include commutative law, associative law and distributive law. Applying these operation laws can make some calculations simple.

The commutative law of multiplication means that when two numbers are multiplied, the positions of the factors are exchanged, and their product remains unchanged. That is, a×b×c=a×c×b. The associative law of multiplication is to multiply three numbers. Multiply the first two numbers first, or multiply the last two numbers first. The product remains unchanged, that is, [a+b]×c=a×c+b×c. The distributive law of multiplication is that when two numbers are multiplied by the same number, it is equivalent to multiplying the two addends by the number, and then adding the two products together. The result remains unchanged, that is, a×(b+c)=a ×b+a×c.
