Funzjonijiet tal-Memorja
- M+ (Memory Plus): Iżżid il-valur muri mal-memorja.
- M- (Minus Memorja): Inaqqas il-valur muri mill-memorja.
- RM (Recall Memory): Displays the current value stored in memory.
- CM (Clear Memory): Iħassar il-valur maħżun fil-memorja.
Funzjonijiet Speċjali
- % (Perċenttage): Użat għal perċentwalitage kalkoli. Per example, to calculate 10% of 200: enter 200, press ×, daħħal 10, agħfas %.
- √ (Għerq Kwadru): Calculates the square root of the displayed number. Enter a number, then press √.
- GT (Total Grand): Accumulates the results of all calculations performed since the last CA or GT press. Press GT to display the grand total.
- MU (Mark-Up): Used for mark-up calculations. For example, to calculate the selling price with a 20% mark-up on a cost of 100: enter 100, press MU, daħħal 20, agħfas =.
