What is the Associative Property of Multiplication?

Back

The Associative Property of Multiplication states that the way in which numbers are grouped in multiplication does not change the product. For example, (a × b) × c = a × (b × c).

Front

What is the Commutative Property of Multiplication?

Back

The Commutative Property of Multiplication states that the order in which two numbers are multiplied does not change the product. For example, a × b = b × a.

What is the Order of Operations?

Back

The Order of Operations is a set of rules that determines the sequence in which calculations are performed. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

How can you use the properties of multiplication to simplify calculations?

Back

You can use properties like the Associative and Commutative Properties to rearrange and group numbers in a way that makes calculations easier.

What does it mean to multiply by 100 to remove decimals?

Back

Multiplying by 100 shifts the decimal point two places to the right, effectively converting a decimal into a whole number. For example, 3.37 × 100 = 337.

What is an example of using the Commutative Property in multiplication?

Back

An example is: 4 × 6 = 6 × 4, both equal 24.

Back

The result is 100.

Back

First, calculate the multiplication inside the parentheses: 20 × 3.37 = 67.4, then multiply by 5: 5 × 67.4 = 337.

What is the purpose of using properties of multiplication in mental math?

Back

Using properties helps to simplify calculations, making it easier to solve problems quickly and accurately in your head.
