Mathematics (or mathematics) is a body of abstract knowledge resulting from logical reasoning applied to various objects such as mathematical sets, numbers, shapes, structures, transformations, etc. ; as well as the relations and mathematical operations which exist between these objects. They are also the field of research developing this knowledge, as well as the discipline that teaches it. They have several branches such as: arithmetic, algebra, analysis, geometry, mathematical logic, etc. There is also a certain separation between pure mathematics and applied mathematics. Mathematics is useful, it is used to understand the world. The first operations, additions, multiplications, make it possible by digitization systems to describe increasingly large numbers
