context_page_description: In mathematics, a multiplication table is a mathematical table used to define a multiplication operation for an algebraic system.
  The decimal multiplication table was traditionally taught as an essential part of elementary arithmetic around the world, as it lays the foundation for arithmetic operations with base-ten numbers. Many educators believe it is necessary to memorize the table up to 9 × 9.
