I'm reading the basic books but this doesn't get explained. Let's have an example: a PC is attacking an AC16 orc with a sword (he's proficient in swords). He rolls a 13 + STR bonus (+ 2) + Proficiency bonus (+ 2) = 17, it's a hit. Now it's the orc's turn, he rolls a 10 (+ 2) STR bonus + ...proficiency bonus??
Very new player here. Looking at the stat block of a goblin: for a shortbow attack it says +4 to hit and the goblin has a Dex modifier of +2.   Does this mean I add 6 to the d20 roll or just the 4 and ignore the Dex modifier?  Same with using Stealth. It says Skills: Stealth +6. So would I take 6 and add +2 of the Dex modifier or just add 6 to the d20 of the Stealth check roll?  Thank you!
If $a$ divides $bc$ and $\gcd(a,b) = d$ then $\frac a d$ divides c I'm trying to prove that if $a$ divides $bc$ and $\gcd(a,b) = d$ then $\frac a d$ divides c. I tried using Bezout identity but couldn't get anywhere. How to install Chromium without snap? I just discovered that chromium will only be released as a snap package.  How can I continue to get chromium, without snap? Is this possible without building from source?  Notes:   Please let's keep to the question as stated - not "what do you have against snap?" I'm not asking how to remove snap (I realize that would break Ubuntu)... just how to use chromium as it is now, a deb.     Update  No, this is not a duplicate of that linked question. I don't need to know "why it's a snap". I want to know how to use it without snap.  Right now there is building from source, and some random PPA mentioned below. I hope someone can advise us of trustworthy alternatives. Sketching base characteristics of first order pde $$xu_{x} - uu_{t} = t$$   with intial data: $u(1,t) = t, −\infty &lt; t &lt; \infty$  So I want to sketch the base characteristics and I'm not too sure what I'm doing.  characteristic equations: $\frac{\partial{x}}{\partial{\tau}}=x$, $\frac{\partial{t}}{\partial{\tau}}=-u$, $\frac{\partial{u}}{\partial{\tau}}=t$  initial conditions:  $x(0)=1$, $t(0)=\xi$, $u(0)=\xi$  $x=e^\tau$ so $\tau=lnx$  Notice that:  $\frac{\partial^2{u}}{\partial{\tau^2}}=\frac{\partial{t}}{\partial{\tau}}=-u$,  This gives me the second order ODE  $\frac{\partial^2{u}}{\partial{\tau^2}}+u=0$  Solving I get:  \begin{align}   u&amp;=c_{1}\cos(\tau) + c_{2}\sin(\tau)\\ t&amp;=c_{1}\sin(\tau) - c_{2}\cos(\tau) \end{align}  From here I don't know what I'm doing? How can I left-align a caption? Better extensible arrows Include the option to flag posts as spam in the Low Quality queue I guess this is an additional to previous requests like  and .  But I just came across  review item, and was unable to flag it as spam.  edit: Since I posted this, the item has been removed (deleted) here is a screenshot: Title pretty much sums it up.  The external style sheet has the following code:  td.EvenRow a {   display: none !important; }   I have tried using:  element.style.display = "inline";   and  element.style.display = "inline !important";   but neither works. Is it possible to override an !important style using javascript.  This is for a greasemonkey extension, if that makes a difference. Circular polarizing filter - slim or regular? I have a Canon EOS 550D. Right now I only have some standard lenses, and I'm looking to buy a Tokina AT-X 116 Pro DX II 11-16mm F/2.8. (I love landscape photography and photography in nature in general.) I want to try using a circular polarizing filter, and I've been looking at the Hoya Filter Circ Pol DMC Pro1 77mm. I can see that the "slim" version is cheaper than the regular one, however, I'm not sure what the difference is. Can any of you tell me which would one be preferable for landscape photography? (I found a thread posted about this some years ago but I would like to hear what you guys think, knowing what camera, lens and filter I'm thinking about combining.)  All feedback would be very much appreciated! :-) Chain length. how long or how many links I measured from the middle of each sprocket and it's 17 inches.

The exact phrase from the book of Swan (the context is choosing the words permit or allow) -      The passive structure with it is only possible with permit   Having said that...

Make me understand this. Rich Snippets not working (and working at the same time?) We have an eCommerce site, and we have had rich snippets implemented (in JSON-LD) since January/February this year (2015). I have read multiple sources (including the Google documentation) and there seem to be three possibilities why they are not showing:   Not enough time has passed (4-12 weeks seems to be the common time quoted) The markup is wrong Google have decided not to show the data   I can rule out the first given the amount of time. The second I am fairly confident is not the case as I have used multiple testing tools. As for the third … well that's anyone's guess (although the study  suggests that MOST shops should be successful).  A strange note is that the rich snippets do not show on a regular search for our ranking keywords (we rank #1 for a few and page 1 for the majority). However the rich snippets DO show when we search for a ranking keyword + site:www.fridgefreezerdirect.co.uk as show here:    I have done this in an incognito window in the browser and using a VPN with the same results.  Can anyone suggest anything we can do or reasons this may be? How do you set, clear, and toggle a single bit? How do you set, clear, and toggle a bit?

One database administrator, one project manager, two programmers and me the front-end designer. This project is an internal reporting system.  Anyways, I've struggling a little bit with my team, the DBA and two programmers seem to control our meetings with what Data we are going to pull and the best way to work it into an object model.  And then look to me to design some pretty interface.  Truth is, we've never measured the objectives of this application and what strategy will best meet them from a front-end design/UX standpoint. We've done no wire frames, no planning of content, no planning of pages, no conversations on specific interface components, nothing like that. It seems my team is content with designing and building the entire UX/UI based on a couple of ideas we've spit-balled in meetings.  Forgive me if this sounds too much like a gripe, but I'm at a loss. How do I get my team to understand, we can't just throw the front-end together based on back-end data and the interface HAS to be well planned out and organized? Prove that : $\displaystyle \lim_{n\to \infty} \frac{1}{n+1}+\frac{1}{n+2}+\frac{1}{n+3}+\cdots+\frac{1}{2n}=\ln 2$    the only thing I could think of is that it can be written like this :  $$ \lim_{n\to \infty} \sum_{k=1}^n \frac{1}{k+n} =\lim_{n\to \infty} \frac{1}{n} \sum_{k=1}^n \frac{1}{\frac{k}{n}+1}=\int_0^1 \frac{1}{x+1} \ \mathrm{d}x=\ln 2$$  is my answer right ? and are there any other method ?(I'm sure there are) What's the difference between the following sentences?
