Complete Guide to Branches of Mathematics: Definitions, Applications
Mathematics is the science of logic, patterns and structures that underpins science, engineering, economics and technology. Whether it’s the simple math people use on a daily basis, or the advanced mathematical models that enable artificial intelligence, mathematics is fundamental to modern life. Knowing its categories can lead users to study many other disciplines in a more organized way, as well as predicting the growth of theory with new problems from real-life solutions.
