Eh, why? This calculater is as barebones as possible. No real functionality a smartphone calc app should have!
Just switch to using something RealCalc
Better yet, disable Google's awful calculator and install RealCalc. It looks much better, functions like a real calculator, and can be used scientifically if needed.
It's a small computer. You don't need a calculator on it to do what you should be opening a spreadsheet for. That said, try RealCalc. Proper RPN mode (optional, plus a lot of options I've forgotten), nice skin, and you can copy the current accumulator (displayed digits or longer internal value), the whole stack, the memory entries, or the last 50 history items, to the clipboard for pasting in other apps (just tap the display window to pop up the copy menu).
I hate the stock Calculator. I removed it with Titanium and installed RealCalc , which I have been using for years.
(It's more advanced than I will ever need, but I love the look and it's functionality)
I'm bouncing between two, different and both good (and free).

proper scientific calculator.

graphing calc, and can switch to regular calc which helps reduce equations. and get a table of values on the graph.
Not sure if these two are the best, but I like them so far.
Oh that would do it.
Try this, I have the pro version that went on sale ages ago for $0.99 or something, don't know what is different in it though

It's everything I and evidently a lot of other people want in a quick access everyday calculator that behaves just like a real physical Casio calculator. It was one of the first Android apps I bought and I'll be really sad to have to give it up.

Has a rather nifty unit converter when you hold down zero. And a ton of other functions.
I've used both, and I don't think the differences are terribly significant. On RealCalc's Google play page there's a list of the additional features. Being able to convert things into fraction form and use Samsung's multi-window features are nice, but I don't think there's anything huge you're missing out on.
RealCalc Scientific Calculator by Quartic Software .. think it was $2.00? Image
It looks boring as crap. Here it is compared to the Windows 1.0 version : http://i.imgur.com/Ug3CcFy.png
Hopefully the RealCalc people eventually make a Windows version: https://play.google.com/store/apps/details?id=uk.co.nickfines.RealCalc&hl=en
Neat calculator from CM that for some reason lacks 1/x function. I use RealCalc from the Play Store. This one also has a very useful feature (to me) to automatically prevent the phone from going to sleep and turning off screen when the app is open.
My go-to "the phone already does this, but..." apps:
RealCalc - Feature-rich scientific calculator. Remember that time you needed to multiply a distance by pi, convert it from feet to meters, and then from decimal to binary, and then repeat the process binge more times and save each to an individual memory slot? I know, that comes up all the time.
PowerAmp - Because fuck every stock music player.
QuickPic - Simple galley app. It got bought by some company a while back, but they haven't destroyed it with bloat yet.
Business Calendar 2 - Solid calendar replacement, very configurable. There's also an older version if Material Design isn't your thing.
FBReader - Open source eBook reader, handles every format you can throw at it. The paid version even does CBZ/CBR files, though a dedicated comic book reader does it better. Better enough than the Kindle app that I go to the trouble of stripping the DRM from all my paid eBooks to use this app instead.
Timely - Alarm clock app that syncs your alarms, supports a "soft wake up" alarm, puzzle unlock, and can diminishing snooze times. The only feature it lacks is a "skip next alarm" button if you, for example, don't need to get up for work next Monday because it's a holiday. Though there is a notification that gives you that option half an hour before it goes off, which is pretty handy.
Nova Launcer - Replaces your home screen, very configurable, and let's you keep a consistent UI across devices regardless of manufacturer, which is nice if you care about that kind of thing, which I do.
Solid Explorer - Every bit as functional as ES File Explorer and then some, but not being slowly filled with bloat.
My "why didn't my phone come with this" apps:
DroidEdit - Text editor, integrates with Dropbox, Drive, and I guess some other cloud services that I don't use.
GPS Test - Just raw GPS data. Gives your location, altitude, speed and time as accurately as your phone's GPS can manage.
WiFi Analyzer - Maybe your wireless network would work better if you weren't sharing the same channel as every other network on your block? Just a bare bones Wifi visualizer.
Unified Remote - Does what it says on the box. Allows you to remotely control a PC, and functions as a universal remote if your phone has IR and you have the patience to program the remote from scratch. Not perfect, but works really well as a remote for my HTPC and TV.
I use RealCalc when my HP-35s isn't handy.
RealCalc is also great, if you don't need graphing.
And RealCalc if you want an oldschool scientific calculator...
If you want something better looking with RPN try Realcalc
Try RealCalc. It's not material, but still beautiful and it's the most usable calculator I've found.
I've been using the paid version of RealCalc for years now and have never had to look elsewhere.
RealCalc is my favorite.

I have an app on my phone that has a very convenient converted built in, as well.
I like RealCalc.
I use RealCalc, and I think it might check most but not all of your requests

Termite Termite for serial comms, has some nice features that resemble qmodem.
PDF Exchange Editor - Free version but I finally paid for the extra features.
Master Converter - Been using this for so long I can't remember, not free.
My #1 util by far is Beyond Compare, this gets the most use everyday.
TCC LE - cmd replacement, been using for over 20 year when it was 4dos.
I could keep going but this is top of my list.
I'd recommend RealCalc. It's not material design but I'd say it looks nice and the more traditional physical style layout is easier to use, imo. It has a landscape mode, unlimited or traditional stack, and quick and easy base and unit conversions which I find pretty handy.
You could also try something like free42 with a custom skin. I use the light version of this one on my work iPhone. You might have to look around for one that fits your aspect ratio; I'm not sure how that works on Androids.
Check out RealCalc on Android for RPN goodness. Sweet keeb.
I use Realcalc
I've always liked RealCalc - https://play.google.com/store/apps/details?id=uk.co.nickfines.RealCalc
I use RealCalc Scientific Calculator and so far no adverts.

It doesn't even HAVE the Equal key! ;)
I've been using the calculator more over the last few days, and definitely see what you mean; it's becoming more familiar to me now. I was going to suggest adding a tutorial, but (barring any new, complicated features) it really doesn't require one as it's a simple calculator.
As for more feedback, firstly I'd like to expand on my initial comment. You may want to integrate both the fraction key and division key into one, which would allow for one less button and likely make things a bit easier to type. If you do go that route, you would have to add a fraction–decimal conversion button, but you may be able to make it context-sensitive and only appear when a fraction can be converted, or vice-versa.
And in that vein, you can most likely do some interesting things with the button layout itself. At the moment, it's emulating that of a physical scientific calculator, which is all well and good, however perhaps you could make it more dynamic? Perhaps change some of the buttons as the situation itself changes, like above? This could be tough to do, or not really useful, though.
Also, you can likely enlarge the buttons by removing the 2nd and 3rd function labels. Maybe have them appear over top of the buttons only when their respective triggering keys are pressed? In addition, I like the solution other apps have come up with, (such as RealCalc) in which to trigger the second function, you can simply long-press on the buttons themselves. This could be very useful for the backspace/clear buttons. You could combine the two and have a backspace button which deletes everything if it's long-pressed. Also, for the 3rd functions, you could implement something like what many keyboards have when selecting accented characters; when a key is long-pressed, a few options come out, and the user can slide their finger over to whichever one they want and release to select it.
Finally, you could combine the answer and input fields, by making the answer appear on the line right after the input, rather in its own box. That way, the user can directly use the answer in their next input, which I find is much easier than having a generic 'ANS' in the equation. Being able to actually edit the equation along with the answer from previously (maybe it could be bolded, to differentiate it from the rest of the numbers?) would be awesome. As well, it would be great to be able to move the cursor by touching it, as well as by the arrow keys. It just gets a little repetitive tapping those keys for long equations (though maybe a long-press on the forward and back could move the cursor to the end and beginning of the input field, respectively?)
Anyway, this is my feedback so far, apologies for its length! Feel free to disregard any or all of it if it doesn't match the vision you have for the app. Let me know if you'd like any clarification on the above, as well. Also, I'll keep using the app, and let you know any further feedback I have (if you don't mind)!
It depends on what exactly you are looking for, but here are the ones I've used and can recommend
Edit: You probably won't want to use Wolfram Alpha for basic calculations, though. Its interface is really made for more complex queries, so I find it easiest to use Xlythe's calculator for your numeric, non-symbolic things, and Wolfram Alpha for more complicated things like manipulating equations.

Excellent calculator app with RPN mode
(Not a graphing calc though)
RealCalc is the closest thing to my HP-32 SII - and it is RPN!
