# MathEntry – Conditional criterium

A more general criterium than equality checking is the criterium based on a condition. Such a condition could be: “the input must be a positive number”. This can be written mathematically as $var>0$, where $var$ represents the student input.

The following example shows a stage that matches if the student input is an integer and even number.

You can define multiple conditions. The evaluation criterium matches when all conditions are valid.
