Quantum mathematics is just the math behind quantum mechanics--> as mentioned above, all about the small stuff. So unless you want to know how to deal with quantum-scale behavior, it isn't beneficial in the slightest.
It's really just an application of calculus, differential equations, linear algebra, fourier analysis, probability and statistics, etc.
As far the above link goes, it's an _okay_ intro to QM. Planck didn't discover that everything was quantized (just light), the suggested link between consciousness and QM is very tenuous and highly controversial, etc.
