The one-handed calculator provides an intuitive feel with simple calculator functions. It is capable of performing simple four arithmetic operations as well as more difficult calculations such as those involving positive and negative numbers. This one-handed calculator allows the user to change the dominant hand (two-handed or one-handed) setting from the settings screen, so the buttons can be positioned left or right in one-handed mode. By having the numbers and four-way buttons on the left and right, it is easier to press the buttons with one hand.
