## The law of quadratic reciprocity ‘or’ statement

I have just seen written that $$(\frac{17}{101})$$ = $$(\frac{101}{17})$$. But doesn’t the law of quadratic reciprocity state that $$(\frac{p}{q})$$ = $$(\frac{q}{p})$$ if $$p\equiv1 mod 4$$ OR $$q\equiv1mod4$$?

## What should i expect after editing lockscreen appearances. emediate changes or..?

I recently switched from windows to ubuntu, and as a web developer i am pretty familiar with the ubuntu gnome-shell css. i tried modifying first by running file explorer as an admin. I made the changes but nothing takes effect even after rebooting, when i check the edited source code, the changes are saved but no results. is there some kind of thing to do that validates the edited version or i went wrong somewhere? I just prefer my user login image rounded rather than with 3px radius. Help pls.

## How ‘AND’ and ‘OR’ can be combined in advanced twitter search operators?

I want to find tweets including one of these three possibility in search results:

• AAAA” and “BBBB

or

• AAAA” and “CCCC

or

• AAAA” and “BBBB” and “CCCC

I mean that AAAA should be in tweets results and one (or both) of BBBB and CCCC should be included too.

How AAAA, BBBB and CCCC should be arranged using one AND operator and one OR operator to get the described result?
