Same here. Even to understand the theory, the only maths tools you really need are differentiation of composite functions (derivatives of f(g(x)), taught in high school ), what a gradient is (taught in 5 minutes if not taught in high school), basic matrix operations (and I mean really basic ones like transposition, nothing fancy like finding kernels) and then you can undertand stochastic gradient descent. The hardest may be thinking in terms of higher dimension tensors (matrices that have 3 or more dimensions) but that is not even mathematics, just an intellectual effort.
