The relation between two expressions that are not equal
yarga [219]

Answer:

an inequality

Step-by-step explanation:

An inequality is the relation between two expressions that are not equal.  The symbols generally used are less than (<) or greater than (>), as in:

4 > 3 or 4 < 9

That means that each side of the symbol represents a value that  is different from the other side.  The relationship is described with the sign to indicate which side has a greater value.

If both sides have an equal value, then it's an equation.
