**In mathematics, the term "multiplier" pertains to any number by which another number, known as the "multiplicand," is multiplied.** The result of a multiplication operation is referred to as the "product."

Multiplication is one of the four fundamental arithmetic operations, which also include addition, subtraction and division. The multiplication sign is usually denoted by the letter "x." This operation basically involves the repeated addition of one number to itself for a specific number of times.

In the multiplication expression 5 x 4 = 20, 5 is the multiplier, 4 is the multiplicand and 20 is the product. Using the long form addition process, this expression can also be written as 4 + 4 + 4 + 4 + 4 = 20. Multipliers and multiplicands are also called "factors."
