All cases rewritten in the form of <em>difference</em> expressions are listed below:

  1. <em>x - 1/2 = 0</em>, <em>x + 1/3 = 0</em>
  2. <em>x + 3 = 0</em>
  3. <em>x - 5 ≤ 0</em>
  4. <em>x + 1/3 ≥ 0</em>
<h3 /><h3>How to translate equalities and inequalities into difference expressions</h3>

Equalities represent relationships between two expressions, in which one expression is equal to another. An equality (<em>x = a</em>) is equivalent to the following <em>difference</em> expression:  

<em>x - a = 0</em>   (1)

And inequalities represent relationships between two expressions, in which one expression is not necessarily to another. An inequality (<em>x < a, x > a, x ≤ a, x ≥ a</em>) is represented by the following <em>difference</em> expression:

<em>x - a = b</em>   (2)

Where b have the following cases:

  1. If <em>x < a</em>, then <em>b < 0</em>.
  2. If <em>x > a</em>, then <em>b > 0</em>.
  3. If <em>x ≤ a</em>, then <em>b ≤ 0</em>.
  4. If <em>x ≥ a</em>, then <em>b ≥ 0</em>.

Now we proceed to rewrite each case in term of <em>difference</em> expressions:

  1. <em>x - 1/2 = 0</em>, <em>x + 1/3 = 0</em>
  2. <em>x + 3 = 0</em>
  3. <em>x - 5 ≤ 0</em>
  4. <em>x + 1/3 ≥ 0</em>
