    2-1 Basic Calculations k k k k k Arithmetic Calculations • Enter arithmetic calculations as they are written, from left to right. • Use the - key to input a negative value. • Use the - key for subtraction • Calculations are performed internally with a 15-digit mantissa. The result is rounded to a 10-digit mantissa before it is displayed.
  • Page 3 2 - 1 Basic Calculations • Number of decimal place (Fix) and significant digit (Sci) settings normally remain in effect until you change them or until your change the exponential display range (Norm) setting. Note also, however, that Sci setting is automati- P.323 cally initialized to Norm 1 whenever you enter the Financial Mode.
