👉 In mathematics and computer science, a concept that refers to simplifying or reducing an expression or problem by removing unnecessary steps or variables. This is often done in order to make the computation easier or more efficient. For example, in evaluating a mathematical equation like "2 + 3", you might simplify it by taking out the parentheses first, then adding the numbers together: ``` 2 + 3 = 5 ``` By doing this, you can avoid performing all these operations at once.
