Hackers 
they are when it comes to math 
Would subtraction also approximate division?
Yes.
Would negation also approximate the reciprocal?
I've always hated that it's called an "inverse". It's not an inverse. The inverse of square root is square. If they had called it "reciprocal", it would have been clear to me what it does, but "inverse" confused the heck out of me when I first saw it.
It's confusing for non-mathematicians, but (and you may know that) it is not incorrect. https://en.wikipedia.org/wiki/Inverse_element "In mathematics, the concept of an inverse element generalises the concepts of opposite (βx) and reciprocal (1/x) of numbers."
Shoulda just called it fast 
mapping()
"inverse" has a very specific meaning: inverse(x) * x = 1, x^2 * x != 1 for any x other than 1. So no, x^2 is not the inverse of sqrt(x)
The inverse is about the negative power right? Square root is the 0.5

I used to think doctors were the dumbest people with "smart people" jobs but it's become increasingly clear that programmers are as a group extremely r-slurred.

Code monkeys should never have been called software engineers because they literally know nothing about any traditional engineering field and act like they do. You can teach an engineer to code but you can't teach a coder to be an engineer.

I've come to the understanding that anyone who can't explain their job/hobbies without injecting a ton of acronyms and jargon you obviously don't get are some of the dumbest motherlovers out there.
Smart people either don't interact with stupid people or if they do, know how to simplify their complex system to the layman.

Yeah a good example of that is Excel. So many r-slurs thnk a long complex spreadsheet with tons of formulas that run on and on means they are smart but smart is doing things as simply as possible and it being easily understandable.

"Yeah bro i wrote this spreadsheet that basically runs the whole business, look at all these formulas. By the way, never use capitals with your inputs, never copy and paste, and also this spreadsheet is shared with everyone so don't make any changes"

People who come from coding make good plumbers. People who come from engineering make good abstractions, and jobs for the plumbers when abstractions encounter the real world and overflow the heap

The only programmers I've met that aren't as r-slurred as me are programers with math degrees.

I mean most normie engineers are pretty smart on the whole but the dumbest engineers are way dumber than any doctor or programmer, like you'll find qtards and flat earthers among that category
