Hi Matthew,
General:
An inequality occurs when we have two values that are not equal to each other, but still have a relationship to one another. (This relationship is an inequality.) We can create an inequality by using the greater than or less than symbols, along with any values of real numbers:
Specific:
Inequality to represent e: e-1>4 Meaning e minus one is greater than four.
Inequality to represent u: u+5<3 Meaning u plus five is less than three.
Best,
