Symbol table

A symbol table is like a book, but instead of having words in it, it has symbols. The symbols can be letters, numbers, or special characters like !, #, or /. Each symbol has a meaning or "value" that the computer can use. For example, the symbol + means "add" and the symbol = means "equals". When a computer program is running, it can look up the meaning of a symbol in the symbol table and use it in its calculations.
