International Journal of Engineering and Information Systems (IJEAIS)   Year: 2021 | Volume: 5 | Issue: 1 | Page No.: 8-17 The Purpose, Function and History Of The Development Of Mathematical Science Usmonov Makhsud Abstract: First of all, it should be noted that the history of mathematics is part of the mathematical sciences. It is well known that although the fields of mathematical sciences are diverse, they are grouped into a single subject under the sign of commonality. This sign of generality can be clearly seen in the definition given to mathematics below. "Mathematics is the quantitative relationship and spatial forms of real being."Different branches of mathematics deal with these quantitative relations and some special cases of spatial forms.
