8 Hobbies That Involve Math and Numbers (To Infinity and Beyond)


They say that math is the language of the universe, but how about the language in which we express ourselves?

Mathematical hobbies often require a particular type of person to either be intrigued by the prospect of working with numbers or to already have a good grasp on mathematical concepts in which they can apply themselves quite easily to such pastimes.

One of the most mind-blowing understandings about our world and everything around us is that it’s built on mathematical principles that are almost hardcoded into the fabric of the universe.

To elaborate, light moves at a set speed (or so we know), gravity can be calculated based on the mass of an object, and nature constantly demonstrates geometrical shapes which most people would assume are random.

Although mathematical principles and concepts are ever-evolving, it’s safe to say we have a good grasp on many areas where maths can be used to predict an exact outcome in relation to the physics of our reality.

Sometimes all it takes is to understand how the math translates to real-world examples to pique someone’s interest which is what we’re hoping to do today with our list of hobbies that involve math and numbers.

8 Infinitely Awesome Hobbies That Involve Math And Numbers

1. Coding

Coding works very much akin to making your own miniature universe and is based on fundamental mathematical concepts (similar to our own reality) to aid in coming up with software-based solutions or to make hardware operate more efficiently or in a certain manner.

The main limitation often starts and ends with the person making the solutions as they can be designed to reach similar results but with varying levels of efficiency or tact.

If you like numbers you’ll be happy to know that coding involves lots of algebra, adding and subtracting, division and multiplication; even things like the laws of physics can be simulated to create models of natural disasters.

Most coding languages know how to execute mathematical instructions and automate the process but the direct input comes from the coder.

If you want what could be considered a sort of mathematical sandbox for a hobby then we think coding is the way to go.

2. Woodworking

If you like the idea of working to exact measurements, using angles, and creating structurally-sound objects then woodworking is probably the best hobby to do that which involves using math and numbers.

We’ve previously written some articles on woodworking regarding the cost to get started and whether it’s a dying art.

These articles are very informative and are worth looking at if you think you may have an interest in pursuing woodworking further.

As they say, measure twice and cut once — good woodworking is a product of precision which often requires a decent understanding of how to work with numbers.

What’s better is that at the end of all that cutting and measuring you’ll be left with a beautifully functional product that can be used in the home or can be sold for a profit.

3. Bodybuilding

You may look at this suggestion with some skepticism but bodybuilding does actually require a good degree of nutritional accounting.

Anyone can lift weights and gorge on food to get big but if you want to pack on lean, efficient muscle then you’ll need to understand your macro split, food portions, basal metabolic rate, and have the ability to read mathematical data if you use a fitness tracker.

In fact, a lot of successful bodybuilding is a product of counting numbers all day which if you’re already into that then that’s most of the work done for you.

4. Build Models

If you like the idea of working to scale and want to see the result of mechanics in action then taking up a model-building hobby is a great pastime to satisfy that curiosity.

In fact, building a model of something usually requires precise measurement to make sure it’ll work efficiently; to aid in that effort, they’re usually manufactured to a like-for-like ratio to the real-life version of whatever it’s a model of, only scaled down.

The reason for maintaining specific ratios when building replica models is to maintain efficiency, aerodynamics, and general balance.

If you want to get started, you can pick up a 1/32 scale model kit of the famous F-16 fighter jet which is absolutely fantastic to look at when completed.

5. Music Theory

If you’re wanting to learn an instrument or music theory, in particular, you’ll soon find out that it actually involves a lot of math in the sense that patterns are inherent throughout the areas of music.

Patterns, scales, and frequencies are all part of the science of music which is intertwined with mathematical concepts that are core to how it all works.

Here is a beautiful publication from Saloni Shah at the University of Manchester explaining the relationship between math and music.

6. Microsoft Excel

Microsoft excel is something everyone should learn (since we all claim to be proficient at it on our resume) but often put off doing in favor of relaxing at the weekend.

In case you didn’t know, Excel is a software program designed by Microsoft that involves using spreadsheets to produce data on or to at least help make the data processing more efficient.

This involves having a good knowledge of algebra and fundamental math skills to get the best out of it as you will need to build formulas into your tables to automate number crunching processes.

With that said, it’s not always used for these types of serious purposes and can actually be used for making fun little games too, similar to how coding works.

In fact, in Excel, if you’re creative enough you can make almost anything you can imagine by using math as a basis.

7. Billiards

Billiards is the defining term for sports played with a cue such as Pool.

Cue sports require you to have a good understanding of mixed concepts, many of which are based on math, such as spatial awareness, orientation, angles, general physics, momentum, and other core mathematical concepts that are inherent to the sport.

Although you’re not necessarily putting pen to paper to make calculations, billiards is served better when you have a deeper understanding of how these concepts work and how you can apply them in a situation such as when you’re trying to pot a ball.

It’s also a good hobby to make some money off your friends if you’re any good at it.

8. Blogging/Webmastering

Blogging is a great way to make some money and you can also write about almost anything including your love of math.

However, and more directly, blogging for a domain has many responsibilities including being able to read or interpret data from various analytics services which usually require a good understanding of mathematical concepts to be leveraged.

Basically, if you can understand and interpret the mathematical concepts within data then you’re way more likely to drive a very profitable business or side hustle like blogging which is very data-oriented.

This data can also be interlinked with other number-based hobbies like coding and using Microsoft Excel to form spreadsheets.

If you’ve been thinking about starting a website or a blog then it’s never been easier than to do it now.

That’s because services like Dreamhost offer competitive packages to get you started and also do “one-click installs” meaning they’ll sort out all of the technical stuff for you to get you up and running.

Frequently Asked Questions About Math-Based Hobbies

Am I good enough to do a math based hobby?

Being good at math isn’t always the most important factor when it comes to picking up a math-based hobby.

Having a burning enthusiasm for something will always end up being the most important factor in whether you will succeed in your endeavors.

Math can start with the most basic things such as adding up all the way to more complex equations.

Hobbies that involve math usually have basic starting areas meaning you can slowly build your way up as you grow more confident.

How can I increase my understanding of math and numbers?

There are plenty of free YouTube videos that can help to explain specific examples of mathematical concepts to help you get a grasp of them.

With that said, if you’re just wanting a general overview then you can pick up this math book to help you get started or to refresh you on some concepts you may have learned in school.

Once you have the tools then all you need to do is practice regularly to help further your understanding and to keep it fresh in your mind.


Hopefully, now you should have a better understanding of what hobbies involve math or numbers.

In reality, data and numbers can be applied to basically every hobby if you want to talk semantics.

Most people can engage in math-based hobbies provided they have some foundational mathematical skills or know-how to apply themselves to learn more advanced concepts.
