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).

What does the term 'factors' mean in multiplication?

Back

Factors are the numbers that are multiplied together to get a product. For example, in 6 x 7, both 6 and 7 are factors.

Front

What is the product in multiplication?

Back

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

How do you multiply two-digit numbers?

Back

To multiply two-digit numbers, you can use the standard algorithm: multiply each digit of the first number by each digit of the second number, then add the results.

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, 4 x 5 = 5 x 4.

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 12, helping students learn multiplication facts.

Front

What is the distributive property of multiplication?

Back

The distributive property states that a number multiplied by a sum is equal to the sum of the products. For example, a(b + c) = ab + ac.

Front

What is an array in multiplication?

Back

An array is a visual representation of multiplication using rows and columns. For example, 3 rows of 4 objects each represent 3 x 4.

How can you check your multiplication answer?

Back

You can check your multiplication answer by using the inverse operation, which is division. For example, if you calculated 6 x 4 = 24, you can check by doing 24 ÷ 6 = 4.
