... At that time, the multiplicand or divisor is stored together with the mode, constant calculation mode. When this key is pressed immediately after the [´] or [MI+, MII+, MI-, MII-] key, operation is the same as that for the [=] key; that is, adds/subtracts using data in memory. This key operation increments or decrements the item counter for memory. TC83230-0015 8 2003-03-04 ...
