The multiplication is an operation which is expressed by sign × (times). In computational technology, we use sign * (asterisk). It is a counting operation which determines the product by two numbers according to its definition. We work out the multiplication of two natural numbers a and b like we add the b number repeatedly the a number times.
4 × 5 = 4 + 4 + 4 + 4 + 4 = 20
The multiplication is the commutative and the associative property so we can write:
4 × 5 = 5 × 4 = 5 + 5 + 5 + 5 = 20
