Your knowledge of the alphabet and multiplication tables is most likely to be stored in your memory.

    Semantic memory

Explanation:  Semantic memory in psychology is known as the ability to memorize numbers, words, terms, letters, and in this memory the information necessary for understanding and using the language and alphabet is stored. Semantic memory is the type of explicit memory and represents our memory of facts, events, ideas, concepts, and a single preserved fact in semantic memory can be invoked at any time. Information that is stored in semantic memory is universal and does not forget, because this information concerns what we know all our life, and what once learned and remains forever as information.

Accordingly, this type of memory differs from episodic memory, which represents certain experiences from our lives, which we can remember, but we do not have to.
