Use your Galaxy phone's Calculator, Calendar, and Clock apps

The Calculator app features both basic and scientific math functions, as well as a unit converter. You can use the Calculator app the same way you'd use a physical calculator. To access the Calculator, swipe up on a Home screen to open the Apps screen, and then navigate to and tap Calculator. Along with its basic functions, you can also use the following options:

• History: Tap the History icon (it looks like a clock) to view past calculations you’ve made.
• Unit converter: Tap the Unit converter icon (it looks like a ruler) to convert different measurements.
• Scientific mode: Tap the Scientific mode icon (it looks like a box with numeric symbols) to display additional function keys.
