Addition Property of Equality and Inequality
Definition of Addition Property of Equality and Inequality


  • Addition Property of Equality:
    If the same number is added to both sides of an equation, the two sides remain equal. That is,
    if x = y, then x + z = y + z.



  • Addition Property of Inequality:
    Adding the same number to both sides of an inequality does not affect the inequality. That is,
    if x > y, then x + z > y + z, and
    if x < y, then x + z < y + z.


Examples of Addition Property of Equality and Inequality

  • Addition Property of Equality
    a) 3 = 3
    Add the same number to both sides.

    a) 2 < 3
    Add the same number to both sides.
    2 + 1 < 3 + 1
    i.e. 3 < 4. Its true.
