Inequality signs
There are four main inequality signs you need to know about:
- < : less than
- > : greater than
- \leq : less than or equal to
- \geq : greater than or equal to
Less than
The < symbol means that the value/expression on the left is less than
the value/expression on the right.
Example: x < 5
This means that 3 is less than 5.
Greater than
The > symbol means that the value/expression on the left is greater than
the value/expression on the right.
Example: y > 2
This means that y is greater than 2.
Less than or equal to
The \leq symbol means that the value/expression on the left is less than or
equal to the value/expression on the right.
Example: a \leq 10
This means that a is either less than 10 or equal to 10.
Greater than or equal to
The \geq symbol means that the value/expression on the left is greater than
or equal to the value/expression on the right.
Example: b \geq 7
This means that b is either greater than 7 or equal to 7.
