What is math?

Math is the study of numbers, shapes, and logic. It’s using fractions to double a recipe. It’s applying theoretical reasoning and patterns to understand the movements of atoms. It’s the foundation of every system we have, from money to medicine.

Math is an academic discipline and an everyday necessity. Whether you’re calculating how long a trip will take or doing advanced data analysis to grow your business, understanding math helps you get ahead.

Innovations in math have powered real-world advancements across society. Engineers, scientists, and medical researchers make the calculations that drive discoveries, from new lifesaving medicines to sustainable building materials.

Math is also fascinating and rewarding in its own right. Professional and amateur mathematicians dive deeply into theoretical subfields such as number theory, learning about previously discovered quantitative concepts and developing new mathematical ideas along the way.

Why learn math?

Math shows you how the world works. Everything in the universe, from the movements of galaxies down to the motions of atoms, is governed by mathematical principles. A math education can help you to understand these principles that guide the world you live in.

Studying math develops your mathematical thinking and problem solving abilities. You learn how to look at a problem, consider the relationships between various factors, and come to a logical conclusion. When you master this thought process, you can reason your way through many of life’s toughest challenges.

A math education can also give you a personal and professional edge. You might use it to calculate a job’s proposed pay, figure out your online business’s profit margins, or compare the employment rates for graduates of different colleges. Whatever your goals, understanding math can get you closer.
