What is multiplication?

Back

Multiplication is a mathematical operation where a number is added to itself a certain number of times. For example, 3 x 4 means adding 3 four times: 3 + 3 + 3 + 3 = 12.

Front

What is the product of 10 x 5?

Back

The product of 10 x 5 is 50.

Front

How do you find the total number of buttons if there are 30 containers with 6 buttons each?

Multiply the number of containers by the number of buttons in each: 30 x 6 = 180 buttons.

Front

What is the product of 3 x 10?

Back

The product of 3 x 10 is 30.

Front

What is the product of 2 x 10?

Back

The product of 2 x 10 is 20.

Front

How do you calculate the total number of seats in a plane with 20 rows and 4 seats per row?

Back

Multiply the number of rows by the number of seats per row: 20 x 4 = 80 seats.

Front

What does the term 'factor' mean in multiplication?

Back

A factor is a number that is multiplied by another number to get a product. For example, in 4 x 5, both 4 and 5 are factors.

Front

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the factors does not change the product. For example, 2 x 3 = 3 x 2.

Front

What is the associative property of multiplication?

Back

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

Front

What is a multiplication table?

Back

A multiplication table is a chart that shows the products of pairs of numbers, typically from 1 to 10 or 1 to 12.
