The commutative property states that the sums and products of values is unaffected by the order those values come in. It allows you to transform mathematical expressions into equivalent forms without altering its value.
Commutative Operations
Addition
The commutative property applies to addition. For any numbers
Multiplication
The commutative property applies to multiplication. For any numbers
Non-Commutative Operations
Operations such as subtraction or division are not commutative:
- Subtraction:
, subtraction is actually Anti-Commutative, meaning, - Division:
- Exponentiation:
- Matrix Multiplication: For matrices
, , and with compatible dimensions:
The anti-commutative property refers to specific operations where switching the order of arguments negates the result of the expression.
Subtraction
Subtraction is an anti-commutative operation. Meaning, for any 2 values
Logical Operations
Some Logical Connectives are commutative, allowing for the rearrangement of variables without changing the truth value of the logical expression.
The commutative property applies to conjunction (AND), for any variables
The commutative property applies to disjunction (OR), for any variables
In set theory, the commutative property refers to how the Union and Intersection of sets are unaffected by the order of the sets they are applied to.
Union
for any sets
Intersection
for any sets
The associative property states that the sum or product of any group of values is not affected by how the values are grouped.
- Addition:
- Multiplication:
