What are the parts of a multiplication problem?

Answer 1

Multiplicand x Multiplier = Product
Most people call the things you multiply factors and the result a product.

In older terminology the things you multiplied were often called multiplicands.

The term multiplier was also often used. The multiplier was often used for the smaller of the two numbers. These days, this distinction is seldom made.

The smaller number is not necessarily the multiplier. These terms were useful when introducing the concept of multiplication as repetitive addition. For example: 3 x 5 ; 3 is the multiplicand (the things to be added), and 5 is the multiplier (how many times you add them up). So 3 x 5 would be introduced as 5 groups of 3 items, or 3 + 3 + 3 + 3 + 3 = 15.
What are the parts of multiplication.

The numbers being multiplied are called "factors" or "multiplicands". The result is the "product"

The names and order they go in are: multiplicand, multiplier, and the answer to the multiplication problem is: product.

OR

if 3 x 5 = 15; 3 is the multiplicand, 5 is the multiplier and 15 is the product.
Factors are what are multiplied to get a product (the result).
