Multiplication and Divison

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).

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 3 (12 ÷ 3) means splitting 12 into 3 equal parts, which equals 4.

How do you find out how many groups can be made from a total?

Back

To find out how many groups can be made from a total, you divide the total number by the size of each group. For example, if you have 20 apples and want to make groups of 5, you do 20 ÷ 5 = 4 groups.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you multiply a number and then divide by the same number, you will return to the original number. For example, 6 x 2 = 12 and 12 ÷ 2 = 6.

If a box can hold 8 items, how many boxes are needed for 40 items?

Back

To find out how many boxes are needed, divide the total items by the box capacity: 40 ÷ 8 = 5 boxes.

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.

Front

How do you calculate the total when you know the number of groups and the size of each group?

Back

To calculate the total, multiply the number of groups by the size of each group. For example, if there are 4 groups of 5, the total is 4 x 5 = 20.

Front

What does it mean to divide evenly?

Back

To divide evenly means that there is no remainder left after division. For example, 12 ÷ 4 = 3 is an even division because there is no remainder.

Front

How can you check your multiplication answer?

Back

You can check your multiplication answer by using division. If you multiplied 4 x 5 = 20, you can check by doing 20 ÷ 4 = 5.

What is the multiplication table?

Back

The multiplication table is a chart that shows the products of pairs of numbers. It helps in learning and memorizing multiplication facts.
