Correct: 10 [+] 5 [=] 15 [÷] 3 = 5

With this method, calculations can be performed in the proper order.

CORRECTING INCORRECT ENTRIES If you press the wrong function key ( +, --, x, or ÷ ), just press the correct function after pressing the wrong one. The calculator preforms the last function pressed.

Example: If you press the 5 + -- x 5 =, the displayed result will be 25 as [ x ] was the last function key pressed.

If you press the wrong number key, press [ ON/C ] once to clear the last entry, or twice to clear all entries made. Entries made with the memory keys are not affected.

If a calculated result exceeds the dis- play ability or the memory capacity, the display stops and E appears in the display. Press [ ON/C ] to resume calculating.
