What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 divided by 4 (12 ÷ 4) means splitting 12 into 4 equal parts, which equals 3.

How do you find the product of two numbers?

Back

To find the product of two numbers, you multiply them together. For example, the product of 5 and 6 is 30 (5 x 6 = 30).

What is a partial product?

Back

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

What is the area model in multiplication?

Back

The area model is a visual representation of multiplication that breaks down numbers into parts to make the multiplication process easier. For example, to multiply 13 by 7, you can break 13 into 10 and 3, then multiply each part by 7.

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you know the product of two numbers, you can divide that product by one of the numbers to find the other.

Front

How can you check your multiplication answer?

Back

You can check your multiplication answer by using division. If you multiply two numbers and then divide the product by one of the numbers, you should get the other number.

Front

What is a multiplication fact?

Back

A multiplication fact is a basic multiplication equation that involves two single-digit numbers. For example, 7 x 8 = 56 is a multiplication fact.

Front

What is the distributive property in multiplication?

Back

The distributive property states that a number multiplied by a sum is equal to the sum of the products. For example, a(b + c) = ab + ac.
