Disabling Your Default Calculator:
If you have multiple calculators installed, go to Settings > Apps > All > Calculator (choose the one you want to hide) > Disable. This will hide the stock calculator from your home screen without deleting it from your phone. To turn it back on, go to Settings > Apps > Disabled > Calculator > Enable. These steps may vary slightly on some phones.
