Long-term memory
Explanation:
There are two common types of memory - Long-term and short-term.
In short-term memory, information are stored just for a very short time before they are eventually discarded or transferred to the long-term memory. It is sometimes called working memory. For example, short-time memory can be used to remember that a particular event is going to be by 12pm today. After the event, the information might either be discarded or pushed to the long-term memory.
In long-term memory, information are stored for a very long term, almost permanently. For example, long-term memory enables you to remember an event that has taken place in the past. In the case of Rasheed, he has so much learned the multiplication tables in such a way that information on the tables have been stored indefinitely in a part of his brain called hippocampus. Every time he needs the multiplication tables, they are always available. So he is already taking advantage of the long-term memory.
