# 21st Century Math Education

Hacking Math Class is the first book of its kind to combine computer programming with learning math. No previous programming experience is required. The book takes you through the basics of getting a computer to do what you want it to do. Then you learn how to apply those programming tools to learning math.

Years ago I taught math to a homeschooled young man who was a computer programming enthusiast. I made sure every homework assignment I gave him contained a computer programming challenge so he could dig deeper into the concepts he learned that week. I got bitten by the programming bug myself and I set out to apply it to every imaginable math topic. In a very short time, I had written Python programs for exploring math topics from Algebra and Geometry to Calculus and Statistics!

Now you can explore math topics like Algebra, Geometry, Trigonometry and Calculus using the Python programming language. You'll learn to create tools like graphers and solvers to help you learn about functions and fractals!

All the code necessary to create the graphics on this page, fractals, 3D models and more are in the book.

Conclusion

## Can't Install Pi3D?

If you have a Windows computer and can't easily install Pi3D, never fear! You can still have fun making 3D Graphics using Visual Python. Just download this version of the 3D Graphics chapter and then install VPython on your computer:

# What is Math Through Technology?

## "Computer Science is the New Mathematics" - Christos H. Papadimitriou

Math Through Technology is a course intended to enable math students to explore math and science topics deeply by using Python programming.

It's not about avoiding math using calculators! It's about automating the boring stuff so you can get to the fun stuff, like Calculus.

### Programming Tools

It's like Minecraft, where you make wood tools, and using wood tools, you can mine stone to make stone tools, and so on. In computer programming you create functions you can use as tools to create more and more powerful tools.

### 21st Century Skills

It's still important to be able to think mathematically.

It's equally important to be able to solve problems using appropriate technology.

### The Python Programming Language

Developed in the late 1990s by Guido van Rossum, Python has become one of the top 3 popular programming languages, with Java and C++. It's widely used in research and industry, and it has applications in everything from web pages (like this one!) to 3D graphics to databases, music and hardware.

While you're learning to solve equations, you'll also be learning marketable skills in a hugely popular programming language.
