Multiplication combines several quantities into a single value, called the product. Multiplication means that the product of x and y is the result of x added together y times.
Long multiplication is a specific way of multiplying large numbers with more than two digits.
In the long multiplication method, the number on the top is called the multiplicand. The number by which it is multiplied (the number at the bottom) is called the multiplier.
