Once BOOLE is launched and the Combinational System chosen, we will give a name to the system and indicate its number of input and output variables and their name. Next, we will activate the option Boolean Expression. In it, we will write any Boolean expression with OR, AND, NOT and XOR (see Help on the screen). When we click of Evaluate the function will be processed, finally we will click on Exit.

Once the function is processed, we can see its truth table by activating in their main screen the option Manual Truth Table.
