The Quick Settings are a quite convenient feature, thinking of it gives you access to different alternatives quickly. With Nougat, the toggles are currently customizable, which should be possible on Marshmallow as well, however it required digging into hidden choices.

How to add calculator in quick setting on Android Nought:
First, head to the Play Store and install the Quick Settings Calculator app. The app is available for free and is only available for Nexus devices because they are the only ones running on Nougat.
Once installed, the app will automatically add a calculator to Quick Settings’ available toggles that you can add manually. The app does not offer any options that you can play with but you can check it out if you want to disable the calculator shortcut or share the app.
Then, just head to the Quick Settings through the notification shade and tap on “Edit“. From the various toggles available to add, press hold at “QS Calc” in the bottom and add it to the Quick Settings page.
Now that the calculator has been added, you can just tap on its icon in Quick Settings and do calculations right in the notification shade.
The feature will be surely convenient for people who are coming from an iPhone, as iOS features a calculator toggle right in the Control Center. The ability to do calculations in the notification center via the calculator shortcut in the Quick Settings is certainly a quicker way, instead of going to the Calculator app. In our testing, the Quick Settings Calculator has exactly the intended effect and gives you chance to do calculations easily.
