A cryptarithm, also known as an alphanumeric puzzle, uses symbols to denote numbers in a number. Unlike algebra, consecutive symbols are treated as a whole number and not multiplied. There are cryptarithms that only contain numbers and no letters. They can be used in addition, multiplication, subtraction, and division.
