Representing Multiplication

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 3 multiplied by 4 (3 x 4) means adding 3 four times (3 + 3 + 3 + 3 = 12).

Front

What are factors in multiplication?

Back

Factors are the numbers that are multiplied together to get a product. For example, in 4 x 5, both 4 and 5 are factors.

What is a product in multiplication?

Back

The product is the result of multiplying two or more numbers together. For example, the product of 6 x 7 is 42.

Front

What is a partial product?

Back

A partial product is the result of multiplying a single digit of one factor by the entire other factor. For example, in 23 x 4, the partial products are 20 x 4 and 3 x 4.

Front

What is an array model in multiplication?

Back

An array model visually represents multiplication using rows and columns. For example, a 3 by 4 array shows 3 rows of 4, which equals 12.

Front

What is an area model in multiplication?

Back

An area model represents multiplication by dividing a rectangle into smaller rectangles, showing how the factors relate to the area. For example, a rectangle with dimensions 5 and 6 represents 5 x 6.

Front

What is a perfect square?

Back

A perfect square is a number that can be expressed as the product of an integer multiplied by itself. For example, 9 is a perfect square because 3 x 3 = 9.

Front

How do you find the product of two numbers?

Back

To find the product, multiply the two numbers together. For example, to find the product of 8 and 7, calculate 8 x 7 = 56.

Front

What does it mean to represent multiplication with an equation?

Back

Representing multiplication with an equation means writing it in the form of a mathematical statement, such as 4 x 5 = 20.

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the factors does not change the product. For example, 3 x 4 = 4 x 3.
