What does the term 'factor' mean?

Back

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

What is the commutative property of multiplication?

Back

The commutative property states that changing the order of the numbers in multiplication does not change the product. For example, 3 × 4 = 4 × 3.

Front

What is the associative property of multiplication?

Back

The associative property states that when multiplying three or more numbers, the way in which the numbers are grouped does not change the product. For example, (2 × 3) × 4 = 2 × (3 × 4).

Front

What is a multiplication pattern?

Back

A multiplication pattern is a sequence of numbers that follows a specific rule based on multiplication. For example, the pattern of multiplying by 2: 2, 4, 6, 8, 10...

How can you use repeated addition to understand multiplication?

Back

Repeated addition is when you add the same number multiple times to find the product. For example, 4 × 3 can be understood as 4 + 4 + 4 = 12.

Front

What is the identity property of multiplication?

Back

The identity property states that any number multiplied by 1 remains the same. For example, 7 × 1 = 7.

Front

What is the zero property of multiplication?

Back

The zero property states that any number multiplied by 0 is 0. For example, 5 × 0 = 0.

What is a number sentence in multiplication?

Back

A number sentence is a mathematical statement that shows a relationship between numbers using an equation. For example, 6 × 7 = 42 is a number sentence.
