Our Top 8 Hobbies That Involve Math and Numbers


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 “deep-wired” into 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.

Top 8 Infinitely Awesome List of 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, and even how 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 “mathematical sandbox” for a hobby then coding is definitely the way to go.

2. Woodworking

If you like the idea of working to exact measurements, using angles, and creating level objects then woodworking is probably the best hobby that involves math.

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 requires 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 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.

Here’s a good video that explains how math and numbers are often applied to the science of bodybuilding:

4. Build Models

If you want to understand or 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 solution to scratch that itch.

Similar to woodworking, model building requires precise measurement to make sure your models work efficiently, and they’re also built with the same ratios in mind compared to the real-life version of whatever you’re working on.

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 then you’ll soon find out it actually involves a lot of math in the sense that patterns are inherent throughout the areas of music.

That is of course if you’re wanting to dive into the deeper side of music which is music theory.

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 of between math and music.

6. Microsoft Excel

Microsoft excel is something everyone probably 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.

Excel is a software programme designed by Microsoft that involves spreadsheets which are often used for producing data on or to help you process data more efficiently.

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 in to your tables to automate number crunching processes.

With that said, it’s not always used for these serious purposes and can actually be used for making games in too.

Excel is similar to coding in the sense that 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 snooker or pool.

Cue sports require you to have a good intuitive understanding of concepts like spatial awareness, orientation, angles, 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 to apply them in a situation to do so such as potting a ball on a snooker table.

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 write about almost anything including math.

With that said, regardless of your topic, blogging or becoming a webmaster for a domain has many responsibilities including being able to read or interpret data from various analytics services.

Data is built on the mathematics of your traffic which means if you can understand it and interpret it well then you can drive a very profitable business or side hustle.

This data can be interlinked with coding and microsoft excel if you know how to use it meaning you can further niche down your understanding of everything that is going on.

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

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

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 an avid interest will always end up being the most important factor of whether you will enjoy doing something in your spare time.

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?

You can watch plenty of free YouTube videos that will explain many specific examples of math concepts to help you get a grasp on 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.
