OPERATION

When you start ADDER, there will be a guide at the top of the screen,
and a short line of equal signs near the bottom.  The number of decimal
positions is two to begin with, however you can press D to be prompted
for the number of decimal places which can range from zero to four.

Enter a number and press either <ENTER> key.

I'll assume you have some positive number showing below the equal sign
line, and that the number you entered has advanced up the screen making
room for you to make another entry on the tape.

At this point you can:

  divide the existing total by a number you enter now by first
   entering the divisor, then pressing the / key.

  multiply the existing total by a number you enter now by entering
   the multiplier, then pressing either the * or x key.

  calculate a percentage of the total by entering the percent you
   want, then pressing the % key.  If you wanted 10%, you would enter
   10%.  You could also multiply by .1 to get the same result.

  add another number by entering the number and pressing + or either
   <ENTER> key.

  subtract a number from the total by entering the number and pressing
   either - (hyphen) key.

  show the total on the tape, and clear the total for a new calculation
   by pressing the <ENTER> key without entering a number.  You can then
   restore the total for a chain calculation by pressing R without
   making any other entry first.  If you start to make an entry, you
   can press BackSpace to delete it and still restore by pressing R.

  set the number of decimal places to use by pressing D and a digit
   from 0 to 4.

  see the percentage that each entry since the last time you divided,
   multiplied, or cleared the total is of the current total by pressing
   P for Percents.

You can use the Backspace key to delete an entry you haven't finalized
by pressing one of the operation keys.
