A Venn diagram is a widely used diagram style that shows the logical relation between sets, popularized by John Venn (1834–1923) in the 1880s. The diagrams are used to teach elementary set theory, and to illustrate simple set relationships in probability, logic, statistics, linguistics and computer science.

These diagrams depict elements as points in the plane, and sets as regions inside closed curves. A Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set. The points inside a curve labelled S represent elements of the set S, while points outside the boundary represent elements not in the set S.
Students then solve mathematical problems in an abstract way by using numbers and symbols. [ 6 ] The development of Singapore math began in the 1980s when Singapore 's Ministry of Education developed its own mathematics textbooks that focused on problem solving and developing thinking skills.
