REvIEwIng & CORRECTIng CalCulaTIOns
A calculation can be reviewed by scrolling back and forth through its contents step by step. While
reviewing a calculation, changes can be made to its values and commands and the calculation can be
re-executed. The
q
and
p
keys can be used with any calculation. However, before the steps in the
calculation Memory can be reviewed, the current calculation must be finalised.
All the procedures in this section are illustrated using the following calculation. Plase note that the
calculation memory can hold up to 100 steps. Each line in the example below represents one step.
