I just figured out TeX integration, so now I can write $y = mx + b$
$$ \begin{array}{lclclclclclcr} 1a &+& 1b &+& 0c &+& 0d &+& 1e &+& 0f & = & 11\\ 0a &+& 0b &+& 0c &+& 1d &+& 1e &+& 1f & = & 12\\ 1a &+& 0b &+& 1c &+& 1d &+& 0e &+& 0f & = & 14\\ 1a &+& 1b &+& 1c &+& 1d &+& 1e &+& 1f & = & 20\\ \end{array} $$
I love math but have always been interested in the trades. Fortunately, mathematics has me covered:
In the mathematical field of geometric topology, among the techniques known as surgery theory, the process of plumbing is a way to create new manifolds out of disk bundles. It was first described by John Milnor[1] and subsequently used extensively in surgery theory to produce manifolds and normal maps with given surgery obstructions.
