If you enter the wrong operator during a calculation, simply press the
correct one to replace it.

When you use the calculator, the number on the top line is the constant
value stored in the calculator (see "Constant Calculations" below). The
number on the bottom line is the calculation.

Standard Calculations

For standard calculations, press the keys in the order they appear in the
arithmetic operation.

Constant Calculations

If you calculate a series of equations with the same number, called the
constant, the calculator lets you perform the calculations without
entering the constant each time.

When you multiply, the first number you enter is the constant.  When you
add, subtract, or divide, the second number you enter is the constant.
The constant value appears on the top line.

Memory Calculations

This memory calculation feature lets you easily do multistep calculations.
For memory calculations, press:

    MR to recall (display) the value in memory.

    MC to clear the memory.

    M- to total a calculation and subtract the total from memory.

    M+ to total a calculation and add the total to memory.

M appears on the upper left side of the display when a number is stored in
memory.

Note:  You can use a constant in percent calculations.
