What is multiplication?

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 4 x 5 means adding 4 five times (4 + 4 + 4 + 4 + 4).

Front

What is division?

Back

Division is a mathematical operation where a number is split into equal parts. For example, 20 ÷ 5 means splitting 20 into 5 equal groups.

Front

What is a product in multiplication?

Back

The product is the result of multiplying two or more numbers together. For example, in 3 x 5 = 15, 15 is the product.

Front

How do you write a division equation from a multiplication equation?

Back

To write a division equation from a multiplication equation, you can take the product and divide it by one of the factors. For example, from 4 x 5 = 20, you can write 20 ÷ 5 = 4.

Front

What does it mean to divide equally?

Back

Dividing equally means sharing something into equal parts so that each part is the same size. For example, if you have 20 apples and 4 friends, each friend gets 5 apples.

Front

What is a group in multiplication?

Back

A group in multiplication refers to the number of times a certain quantity is repeated. For example, in 6 groups of 5, there are 6 groups with 5 items in each.

Front

What is the equation for finding the total number of items in equal groups?

Back

The equation is: Total items = Number of groups x Items per group. For example, if there are 6 groups of 5 apples, the total is 6 x 5 = 30 apples.

How do you solve a two-step word problem?

Back

To solve a two-step word problem, first identify the two operations needed, solve the first operation, and then use that result to solve the second operation.

Front

What is the meaning of 'equal groups' in math?

Back

Equal groups mean that each group has the same number of items. For example, if you have 24 pencils and divide them into 3 equal groups, each group has 8 pencils.

Front

What is the relationship between multiplication and division?

Back

Multiplication and division are inverse operations. This means that if you know one, you can find the other. For example, if 4 x 5 = 20, then 20 ÷ 5 = 4.
