Know the Calculator app in iOS 10

Apple’s Calculator app is one of those stock offerings largely flying under the radar for its soberness. It is somewhat overlooked, but then again can be a lifesaver at times. For those who need to crunch numbers on a more regular basis it is presumably nothing but an emergency fill-in, when for the rest of us it definitely more than cuts the mustard for everyday computations.

On the back of such a broad user base with varying skill sets, it goes without saying that there is a large discrepancy in expertise and knowledge about the calculator app itself.

The fact you can still elicit the occasional gasp from an unknowing iPhone user, just by rotating the interface to landscape mode says a lot about the relevance of calculator to many. Yes, it is mostly a plain calculator representation, but Apple did implement more knacks than first meet the eye. Novice or professional, if you are keen to boost your productivity in calculator, continue reading to find out if you are up to speed on the following tricks:

Math students: how to use your Mac as a graphing calculator

Although your Mac comes with a Calculator app, you will find that it only supports basic, scientific, and programmer modes.

Unfortunately for those who are in advanced math courses in school, be it grade school or college, or for those that just need a hand in tutoring their children, the Calculator app doesn't come with graphing functionality and it leaves you to fend for yourself.

A little known feature of your Mac, directly out of the box, is that it does have graphing functionality built into its default software, and in this tutorial, we'll show you how to unleash it.

Tip: Use your Mac’s Calculator app as a unit converter

You probably think the Calculator app on your Mac is a bare-bones math calculation app used to quickly multiply, divide, subtract, and add numbers, but it can do many other things that are often overlooked.

Although it's great at these kinds of things, did you know your macOS Calculator app is also a full-featured unit converter that can convert one form of measurement to another? For example – converting meters to yards, or inches to centimeters.

In this tutorial, we'll show you how you can use the Calculator app on your Mac to quickly convert a unit of measurement to another.

Mimic iOS 9.3’s new Calculator app Quick Action with this tweak

iOS 9.3 beta includes a new Quick Action feature for the Calculator app, allowing those with a 3D Touch display to press firmly on the Calculator app icon to reveal a new option: Copy Last Result.

Fortunately, those with a jailbroken device on iOS 9.0-9.0.2 don't have to upgrade to iOS 9.3 beta to get this feature. A new free jailbreak tweak called CalculatorCopy is now available in Cydia's BigBoss repository that will bring this feature to older iOS 9 installations.

How to quickly delete digits in Calculator app

I use Apple's stock Calculator app all the time, whether for calculating tips, computing percentages or running complex math in landscape mode—in spite of having a dozen or so third-party calculator apps installed on my iPhone.

I just prefer the convenience of quickly launching the Calculator app via the Control Center without even needing to unlock my iPhone. The problem is, the app doesn't have a delete button. So what do you do if you've typed a wrong digit?

'Oh, I can just start over,' I hear you say. That always work, of course. But as it turns out, Apple's engineers thought of that after all and did provide a neat shortcut to quickly delete a single digit.

Google releases Ivy, an experimental big number calculator for iPhone and iPad
