1. a = b means a is equal to b.

2. a ≠ b means a does not equal b. Operations

1.Addition: If a = b then a + c = b + c.

2. Subtraction: If a = b then a – c = b– c.

3.multiplication: If a = b then ac = bc.

4. Division: If a = b and c ≠ 0 then a/c = b/c.

Reflexive property a = a

Symetric propertyIf a = b then b = a.

transitive propertyIf a = b and b = c then a = c.
