Hi there! I'm Juan Carlos. I am a mathematician living in Brisbane where I teach mathematics and work on the design and integration of online learning modules and interactive mathematical applets. I also create open-source online resources for teaching and learning mathematics.

I am passionate about the beauty of mathematics and bring that passion to life through a unique collection of t-shirts featuring captivating mathematical designs.

I believe that mathematics is more than just numbers and equations—it is a fascinating exploration of patterns and structures that shape our world. My t-shirts showcase the elegance and intricacy of mathematical concepts, allowing you to express your love for mathematics in style.

Join me in celebrating the beauty of mathematics and make a statement with these mathematical t-shirts. ∞ Thanks!
