Entitled: "Haec contemplandis numeris ars gaudet, eorum occulta sollers ervens mysteria". Print created by Cornelis Cort, 1565, showing a woman and two men seated in a room at a table strewn with books, tools, papers, and small discs with markings that might be coins. The woman wears classical robes with numbers decorating the hem and is writing numbers on a tablet. Another person stands behind her chair and points at what she is writing. To the seated woman's right one of the men is also studying a tablet. Across the table from the woman the other man is reading a book. On the ground are two books which are labeled: Abraham and Pythagoras. Two gourds are hanging on the wall in the background. Arithmetic is the most elementary branch of mathematics, used for tasks ranging from simple day-to-day counting to advanced science and business calculations. It involves the study of quantity, especially as the result of operations that combine numbers. In common usage, it refers to the simpler properties when using the traditional operations of addition, subtraction, multiplication and division with smaller values of numbers.
