Extractions refer to the process of removing a substance from a mixture or environment. In various fields, such as chemistry and medicine, this can involve isolating specific compounds or elements for further study or use. For example, in dentistry, tooth extractions involve the removal of a tooth that is damaged or decayed. In the context of data, extractions can mean retrieving specific information from a larger dataset. This is often used in data analysis, where analysts extract relevant data points to gain insights or make decisions. Overall, extractions play a crucial role in simplifying complex systems for better understanding and application.
