Flashcard: Whole Number Multiplication and Division

Front

What is multiplication?

Back

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

Front

What is division?

Back

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

How do you find the number of items in each group when dividing?

Back

To find the number of items in each group, divide the total number of items by the number of groups. For example, if there are 24 apples and 6 groups, then 24 ÷ 6 = 4 apples per group.

Front

What is the product of two numbers?

Back

The product is the result of multiplying two numbers together. For example, the product of 5 and 6 is 30 (5 x 6 = 30).

How do you solve a multiplication problem?

Back

To solve a multiplication problem, you can use repeated addition, arrays, or the multiplication table. For example, to solve 4 x 3, you can add 4 three times (4 + 4 + 4 = 12).

Front

What is a quotient?

Back

The quotient is the result of a division problem. For example, in the division 20 ÷ 5, the quotient is 4.

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 original numbers, you should get the other number.

Front

What is a remainder in division?

Back

A remainder is the amount left over after division when the numbers do not divide evenly. For example, in 10 ÷ 3, the quotient is 3 and the remainder is 1.

How do you find the total number of items sold over several weeks?

Back

To find the total number of items sold over several weeks, multiply the number of items sold each week by the number of weeks. For example, if 10 items are sold each week for 4 weeks, then 10 x 4 = 40 items.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you multiply a number by another number, you can divide the product by one of those numbers to get the other number.
