Math Division and Multiplication Flashcard

Front

What is division?

Back

Division is the process of splitting a number into equal parts. It answers the question, 'How many times does one number fit into another?' For example, 12 ÷ 3 = 4 means 12 can be split into 4 equal parts of 3.

What is multiplication?

Back

Multiplication is the process of adding a number to itself a certain number of times. It answers the question, 'How many in total?' For example, 4 x 3 means adding 4 three times: 4 + 4 + 4 = 12.

What is a picture graph?

Back

A picture graph is a visual representation of data using pictures or symbols. Each picture represents a certain number of items, making it easier to understand the information.

How do you find the total number of items in multiple groups?

Back

To find the total number of items in multiple groups, multiply the number of items in one group by the number of groups. For example, if there are 6 items in each of 20 bags, the total is 6 x 20 = 120.

What does the equation 30 ÷ 5 represent?

Back

The equation 30 ÷ 5 represents how many groups of 5 can be made from 30. The answer is 6, meaning 30 can be divided into 6 groups of 5.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. If you know that 4 x 5 = 20, you can also say that 20 ÷ 5 = 4.

Front

What is the commutative property of multiplication?

Back

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

Front

What is the associative property of multiplication?

Back

The associative property of multiplication states that the way numbers are grouped does not change the product. For example, (2 x 3) x 4 = 2 x (3 x 4).

How do you solve for an unknown in a multiplication equation?

Back

To solve for an unknown in a multiplication equation, you can divide the product by one of the known factors. For example, if 6 x ___ = 30, you can find the unknown by calculating 30 ÷ 6 = 5.

Front

What is a factor?

Back

A factor is a number that divides another number without leaving a remainder. For example, 2 and 3 are factors of 6 because 2 x 3 = 6.
