Bob's Calculator Modes:
Mode 1: The Basic - For the simple math needs of the common man. It adds, subtracts, multiplies, and divides with ease, but don't expect too much more.
Mode 2: The Advanced - For those who need a little more oomph. It does Mode 1's functions and then some: square roots, exponents, and even a hint of calculus. But be warned, it's a bit of a beast.
Mode 3: The Esoteric - For the math wizards. It's got all the modes, plus some Bob's own special sauce: Fourier transforms, fractals, and a pinch of chaos theory. Don't say we didn't warn you.
