Математика на пальцах гифками

Mathematics (ancient-Greek. <Ancient-Greek. Study, science) - the science of structures, order and relationships, historically based on the operations of counting, measuring and describing the shape of objects. Mathematical objects are created by idealizing the properties of real or other mathematical objects and writing these properties in a formal language. Mathematics does not belong to the natural sciences, but is widely used in them both for the exact formulation of their content and for obtaining new results.

Mathematics is a fundamental science that provides (general) language tools to other sciences; thus, it reveals their structural interrelation and contributes to finding the most general laws of nature.

Animation mathematics are not dry graphs and numbers, which are sometimes impossible to understand. These are clear, visual animated pictures of the basic laws of mathematics. Here I looked at the GIF and much, since school, becomes clear. It is interesting to watch even those who do not understand;)
