Question

How do you write an inequality?

Answer 1

You write two equations and a < or > in between them. It could also be with singular numbers.

Answer 2

An inequality is not equal (duh) so it includes signs like
> more than
< less than
< equal to or less than
> equal to or more than

so just write something that is true like

5>4
4>3
3<20
x>39
