Definitions :     
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 property
If a = b then b = a.
 transitive property
If a = b and b = c then a = c.
