m).Memory Minus Key (M-)

i).Subtracts the current display from the contents of memory

ii).It will terminate a number entry.

n).memory Recall and Clear Key (RCM)

i).First push, as RM key, transfers the contents of the memory register into the display register.

ii).Second push, as CM key, clears the memory.

o).Number, Decimal Key ("00", "0 - 9", "•")

The first number key in a sequence will clear the display and enter the digit in the display. Successive entries

Ands the current display to the content of grand total memory.

u).Grand Total Minus (GT-)

Subtracts the current display from the content of grand total memory.

GT- will terminate a number entry.

C). Error Conditions

a).Error Detection

System errors occur when :

i).The integral part of any calculation result exceeds 12 digits.

ii).The integral part of any memory calculation result exceeds 12-digit or when the integral part of any addend

or subtrahend to memory exceeds 12-digit.

iii).The integral part of a mark-up and mark-down calculation result exceeds 12-digit.

v).A division by zero is attempted.

iv).An extraction of the square root of a negative number is attempted.
