Answer:
The answer is working memory.
Explanation:
Working memory is a memory system which allows a person to process and manipulate information. Although it's sometimes used interchangeably with short-term memory, the difference is that working memory allows the person to use the information in a practical way, while short-term memory simply stores it. For example, a mathematical formula stored in the short-term memory will be used by working memory when solving a problem in a test.
