8.7 Inserting a Result or a Calculation.
Suppose that you are writing a letter, and you want to do a calculation and include the result or the
whole calculation in the letter. How would you do that?
You could do the calculation before starting the letter. Alternatively, you could begin the letter and
then use the Task Menu to switch from the Word Processor to the calculator, do the sum and then
switch back to the letter.
When you get to the point in the letter where you want to include the result of your calculation or
the whole calculation, press SPACE with O for the Options Menu. From the Options Menu, select
the Insert option, then from the Insert Menu, select the Calculator result or Calculation option.
KeyPlus prompts: "Insert result or whole calculation?" For the result, press R, or for the whole
calculation, press C.
The most recent result or calculation from the calculator is inserted into the document, which saves
you having to remember and re-type it.
