 Aug 21 comment Computing the standard part of $(3-\sqrt{c+2})/(c-7)$ where the standard part of $c$ is $7$ Yep. I'm a moron. Thanks guys.

Thanks for pointing that out. Apr 15 comment Help verifying my proof that for any $\epsilon>0$, there exists rational $\frac{j}{k}$ such that $0<\frac{j}{k}<\epsilon$ Clarity seems to escape me. I don't know why I didn't think of that.

I barely missed this idea. I was trying to do stuff with conjugates, but didn't quite connect the dots.

I saw those after posting and was going to close, but then people started answering. Still, it's been helpful. Mar 25 asked Proving that $\sqrt{2}+\sqrt{3}$ is irrational
