The following is the truth table of the combination of input A and
B:

The following examples show the answer screen when
executing a boolean operation for AND, OR, XOR,
XNOR between “1100” and “1010” in binary mode.
Compare the results (binary) to the above table.
1. Press # @ V A E to enter the binary,
octal, and hexadecimal calculation mode.
2. Press } } } to select the binary mode.
