👉 In mathematics and computer science, "unpassing" is a concept that refers to a condition where a statement or expression cannot be evaluated as true. It's often used in contexts where one expects an evaluation to occur but it never occurs. For example: 1. If you try to evaluate the following expression: ``` 3 + 5 ``` The result will always be `8`, because evaluating this expression is a valid mathematical operation and should produce a true value.
