Everything around us has patters. some can be eisly found like waves in a pond and others are much difficult to find.
Mathematicians seek and use these patters to formulate new ideas; they resolve the truth or falsity of ideas by mathematical proof. When mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.
Everything you use including your mobile phone and the gas cylinder used to cook food and the electricity to rotate the fan are all developed using mathematics. It is one of the most important subject you should know in the modern world.
