Welcome to ProofWiki! Since you're new, you may want to check out the general help page. It's the best first stop to see how things are done (next to reading proofs, of course!). Please feel free to contribute to whichever area of mathematics interests you, either by adding new proofs, or fixing up existing ones. If you have any questions please feel free to contact one of the administrators, or post your question on the questions page.

Here are some useful pages to help get you started:

• Community Portal - To see what needs to be done, and keep up to date with the community.
• Recent Changes - To keep up with what's new, and what's being added.
• Check out our house style if you are keen on contributing.
• Main Page talk - This is where most of the main discussions regarding the direction of the site take place. If you have any ideas, please share them!

Straight Lines

Your contribution is seriously good. Solid stuff, just needs formatting and structuring. My job, mainly, but feel free to fill in the links if you wish.

Some of the stuff you prove in detail is already covered in $\mathsf{Pr} \infty \mathsf{fWiki}$ (for example $\size x = \sqrt {x^2}$ is one of the axiomatic definitions of $\size x$ in the first place) but this is just details we can polish.

Seriously, good job. --prime mover (talk) 23:06, 25 March 2023 (UTC)

Oh one more thing, please do not use the "Visual Editor" mode of the text editor. That is, please use "Edit source" rather than "Edit" because the latter reformats the source code inconveniently, and you don't have complete control over what you are editing.
