Constant calculations

You can perform "constant" calculations by setting an automatic constant to continually
add, subtract, multiply, or divide. Pressing [+], [ - ], [x], or [÷] twice after inputting a
number, will make that number a constant. "K" will be shown on the display, indicating
that a constant is being used.
For addition, enter [constant] [+] [+]. When you press [=], the constant will be added to
the number on the display. Pressing [AC] clears the constant.
For example: [2] [+] [+] [=]
