If you attempt to enter a value that is invalid for the numeral system you are using, the calculator displays an error message. The current system is specified by SET UP Mode Comp, Dec, Hex, Bin, Oct.
Example 1
To calculate 0 × 1 = 0
0 × 1 EXE 0×1 0
and also 0 × 0 = 0
0 × 0 EXE 0×0 0
Example 2

0 ÷ 1 EXE 0÷1 0
Example 3
To enter 1 ÷ 0
Ma ERROR Press:[EXIT] 1 ÷ 0 EXE AC/ON 1÷0
