Basics:  Using a previous answer

 

  1. To use the last answer as the first number of the next calculation, just enter the operation sign that goes after it.  The calculator will show ANS in the first spot.
  2. To use the previous answer in the next calculation, but NOT in the first position, press ANS  ( 2nd + (-) ) [in the lower right]
