12 reasons why math is important[And how to get better]

The following is a collection of reasons I’ve given students on why it’s important to learn math. If only one of these reasons motivates you to be a better student or makes your job as a teacher easier, then curating this list will have been well worth it.

When I was younger, I wanted to be good at math.

I was friends with many smart kids, and it seemed like I was the only one of my friends who couldn’t understand and apply basic mathematical concepts. I’ve written about my struggles with math in high school and how I improved my understanding of math to the point of getting a Bachelor’s degree in physics with a minor in math.

Part of what helped me grasp math concepts was becoming a tutor for mathematics and physics. Nothing improves your understanding of a subject like helping others to understand it as well. However, I often ran into the same problem.

Many of them were doing terrible because they couldn’t see the point of learning mathematics. I could help them with their math homework, but it would be up to them to take a real interest in their math education if they wanted to do well on tests.

Why is math important for everyday life?

This is the question that I think most teachers wrestle with.

They can see the abstract applications and the technical innovations, but that’s because teachers have the benefit of mastery. The real challenge is getting high school students to see how learning to solve math problems will have any effect on their daily life.

While my job was to improve their math and physics grades, regardless of how they felt about the subject, I found that my task was a lot easier when they were motivated. Motivation comes from a belief in the cause that your actions are supporting.

Therefore, I took every opportunity I could to explain why it was important that they learned math and how it related to the real world. While none of my former students have gone on to become mathematicians, they all understand the importance of math and (I believe) have a deep respect for the power of numbers.

The following is a collection of reasons I’ve given students on why it’s important to learn math. If only one of these reasons motivates you to be a better student or makes your job as a teacher easier, then curating this list will have been well worth it.

Improves ability to communicate

Mathematics teaches you to be very precise with your words and definitions.

People don’t think about the connection between their verbal acumen and their mathematical reasoning, but math is a language. Like any other language, there are rules for communication. The difference between math and most other languages is that math has no ambiguity.

With math, you don’t get to use body language or tone of voice to clarify the message. A mathematical message is objective, precise, and has no ambiguity. Nowhere is this more clear than in computer programming.

Programming languages are nothing more than the instructions for computers, written in math because that’s what a computer understands. You may write the program with words, but the compiler sees the words and, because each word is tied to a specific operation, it’s able to tell the computer what to do in a binary math language.

This is why it can be so frustrating to spend hours writing code for a program or website that won’t work, only to find that it was something so seemingly minuscule as a missed colon, extra space, or wrong case that kept everything from working.

Teaches the value of the process

Math is both objective and you have to prove why it works

In fact, math is unique in that you need to not only have the correct outcome but also demonstrate the soundness of the process that you used to arrive at that outcome.

Even in lower-level math classes that most of us are familiar with, this is the idea of “showing your work”. Any math teacher worth a damn will not let a student get away with just coming up with the right answer, but arriving at it via a terrible process. In fact, you typically receive more credit if you have a sound process but get the wrong answer than vice-versa.

This feature of mathematics is used to verify (or debunk) many experiments in the social sciences because it’s been shown that the processes they used, when repeated, don’t produce the same outcome. This is a reformulation of the same question that the scientific method puts to the test: does the process produce the same outcome every time?

If it can’t do that, then the conclusion is at best, considered pseudoscientific and at worst, classified as fraudulent.

Keeps you from being fooled

The stronger your grasp of mathematics, the harder it is for people to take advantage of you.

When you sit in on someone’s pyramid scheme pitch, you’ll be able to instantly tell that the numbers simply don’t work. While everyone else is excited about the prospect of going from nothing to 18 months by recruiting 5 people who recruit 5 people who recruit five more people, you will immediately recognize that this only works if each person spends $1000 on something that they can get for $50 elsewhere.

While everyone is being manipulated by the media’s latest rising figure of murder and disease, you’ll be able to immediately recognize that they used the metric that sounds the most terrifying to fit their agenda.

Math makes you more money

If you’re wondering what to major in to get the greatest return on your college tuition, here’s a simple test: does the major require you to study at least one level of calculus? If it doesn’t, you’re probably wasting your money in college studying it.

A look at the Glassdoor.com list of the 50 highest paying majors by starting salary, Nursing is the only major that doesn’t require Calculus that starts above $50,000/yr. But if you’re thinking about studying nursing to earn a better salary without facing the rigors of mathematics, you’ll still have to take statistics which is just as challenging and academically rigorous.

Improves your quality of life

We live in a world that is run on technology and information.

It’s been said that in the 21st century, “data is the new oil.” It stands to reason that the best jobs—the ones willing to do the most to retain employees as well as pay higher salaries—are in career fields that involve technology and data.

Technology development and data analysis are fields of hands-on applied mathematics.

Business Insider’s list of 14 High Paying Jobs with Work-Life Balance includes 10 professions where math is either directly used or mathematical reasoning is used in programming. The future will be dominated by math and technology. This makes math an important subject for anyone who wants to make a lot of money but doesn’t have an interest in working for themselves or starting a business.

Math sharpens your analytical thinking

Math is based on logic.

The word “math” is derived from the Greek word “máthēma” meaning “knowledge, study, learning.”

Math forces you to think deeply about what you see and come up with adequate language to explain it. You have to make sure that your reasoning is sharp enough to not only articulate what you know but to frame it in such a way that a person could follow what you’re saying and repeat what you’ve done. That’s the type of clarity that is demanded in mathematics.

In fact, this is the basic idea behind a theorem. They’re based on proofs, which try to prove some conclusion by walking through you a set of premises and logical reasoning. Though you will likely never get into mathematical proofing, the idea is still relevant for arguing your ideas and analyzing the arguments of others.

Makes your thinking more rigorous

A mentor once told me that a definition of science is a set of predictions that are testable, repeatable, and mathematically verifiable.

This means that if I make a prediction or a declaration, I should be able to construct a mathematical rule that tells me how often and under what conditions the outcome it predicts will occur.

When we sidestep this level of rigor, academically or casually, it’s easier for us to fall prey to biases. This decreases the possibility of us achieving our goals or understanding one another.

A solid understanding of mathematics will intuitively lead to the idea that you need to have clear definitions and hypotheses for things you want to understand and explain.

Develops problem-solving skills

Most of us will never need to use the Pythagorean theorem or solve a quadratic equation in real life. However, the approach you take when you learn these skills transfers over into other problem-solving endeavors.

This is not to say that you’ll be a terrible problem solver if you can’t do high school algebra. It only means that the meticulous approach to doing mathematics translates into many other skills.

Basic math skills are required to survive in this world

No matter how powerful or portable or calculation devices become, we still need to understand math so we avoid issues like the one above.

You need to understand how to give the correct change; not because you might be working as a cashier one day, but because you will buy things and you need to know if they’re giving you the right amount back.

You need to understand how to follow a recipe. There’s a big difference between ⅓ and ⅔ when it comes to measuring out food. In fact, in 1980 A&W introduced a rival to McDonald’s quarter-pounder (¼ lb) that was a ⅓ pound of meat at a better price, but it failed because people thought ¼ was bigger than ⅓ and they were being overcharged.

Read more about what happens when a population lacks mathematical knowledge here.

In his book, Threshold Resistance, Adolph Taubman looked back on this whole situation. He states: “More than half the participants of the Yankelovich focus groups questioned the price of our burger. “Why,” they asked, “should we pay the same amount for a third-pound of meat as we do for a quarter-pound of meat at McDonald’s? You’re overcharging us.”

The future is mathematical

As the world becomes more digital, skills like web design, engineering, and programming will continue to rise in value. The ability to analyze data and write algorithms that allow internet marketers and eCommerce stores to make money already command higher salaries than most professions.

Speaking of medicine and science, all advances in communication and technology are based on quantitative reasoning and mathematical understanding. We are now solving complex problems and to do so, we need math.

Even for relatively simple work like the skilled trades, there is heavy reliance on mathematical reasoning. The digital/scientific nature of the world relies on math as well. This leaves few options for a well paying, satisfactory profession moving into the future.

Learning math makes you better at everything else

Studies have shown that students who are better at math have more grey matter in their brains.

The grey matter throughout the central nervous system allows enables individuals to control movement, memory, and emotions. Different areas of the brain are responsible for various functions, and grey matter plays a significant role in all aspects of human life.

If you have better control of your body, mind, and emotions, you have better control over your world and you’ll be better able to do everything better.

Math helps you to navigate uncertainty

Even a basic understanding of odds and probability can help you do better at (or avoid entirely) games of chance and gambling.

It also opens up the world of sports betting and allows you to better assess the safety of an activity. Understanding odds, ratios, and percentages not only opens up a possible income stream in the form of sports betting or financial trading but also gives you a more accurate understanding of how the world works.

You begin to understand that the world is more probabilistic than deterministic in nature, and your thinking becomes more nuanced. This makes your predictions more accurate and your decisions more precise.
