logic gates functions

[taha24]

this a four logic gate contains the logic : AND, OR and NOT, and it suppose to take four in put and divide them into to numbers and add them together like this : the input is ( 1 0 1 1 ) divide them to ( 10 + 11 ) equal to ( 0 1 0 1 ) and convert it to decimal which equivalent to ( 2 + 3 ) equal to ( 5 )
anyone know something please do ...
