u Editing Calculations in the Math Input/Output Mode
    The procedures for editing calculations in the Math input/output mode are basically the same 
  as those for the Linear input/output mode. For more information, see “Editing Calculations” 
 (page 1-6).
    Note however, that the following points are different between the Math input/output mode and 
  the Linear input/output mode.
  • Overwrite mode input that is available in the Linear input/output mode is not supported by 
  the Math input/output mode. In the Math input/output mode, input is always inserted at the 
  current cursor location. 
  • In the Math input/output mode, pressing the D key always performs a backspace operation. 
 • Note the following cursor operations you can use while inputting a calculation with Math 
 input/output mode. 
  To do this:   Press this key:  
 Move the cursor from the end of the calculation to the beginning 
e
 Move the cursor from the beginning of the calculation to the end
