Most people never think about where a calculator's math actually happens. The math tools section grew out of the same idea. I left all six in because people genuinely have preferences. The pastel theme was the first one I actually liked using for extended periods – soft enough that it doesn't strain your eyes, but still clearly readable. The six themes came later, after I noticed I was using the calculator for long stretches during homework sessions. I just wanted to punch in sin(45) and move on with my life.
