Fractions and properties of addition

Associative Property

Commutative Property

Distributive Property

Identity Property

Step-by-step EXPLANATION

ASSOCIATIVE PROPERTY

In this property, irrespective of the regrouping between a number and the addent within a bracket, the sum, value does not change.

For example:

(A + B) + C = A + ( B + C)

COMMUTATIVE PROPERTY

In commutative Property, you will always get thesame results after changing the order or position of the addent.

For example:

A + B = A + B

Also,

A + B = B + A

DISTRIBUTIVE PROPERTY

Basically here, please note that, the sum (addition) of two numbers times a Third one is always equal to the sum of these numbers times the third one.

For Example:

A x (B + C) = AB + AC

IDENTITY PROPERTY

This property is the easiest of all, it simply says that "Add a number to Zero must always be that number".

For example:

A + 0 = A

B + 0 = B

C + 0 = C
