Personally, that's how most of my math learning came. As a teen, I started to program and wanted to understand mathematics tools to solve specific problems, so I learned trig, Bezier curves, cryptography, number theory, etc like this. Then later between my love of point and click adventure games and puzzles plus the fact that I had good foundations in maths, pure mathematics problems became increasingly fun.
