To make a full subtractor, you need an XOR and a NAND gate.
xor and xnor gates are derived from not gate
yes... xor is derived gate from primary gates
No, XOR gate is a not a universal gate. There are basically two universal gates NAND and NOR.
its not
a XOR bis equivalent to: (a AND NOT b) OR (b AND NOT a)
XOR (Exclusive OR) gate is exclusively for either. OR allows 10, 01, 11. XOR allows 10 or 01, but not 11.

1 gate.
the easiest way to make an xnor gate is with a 7486 (or equivalent) integrated circuit, a quad xor gate. connect the output of one gate to one in put of another gate. connect the other input of the second gate to Vcc. the second xor gate will then act as an inverter.
XORing X with 1 gives X', i.e., NOT(X). If we are able to construct a NAND (AND) using XOR, we can also obtain AND (NAND) from it, which makes XOR a universal gate since inverted inputs to a NAND (AND) will give OR (NOR). However XOR is not a universal gate! Therefore we cannot obtain NAND (AND) using XOR. :-) By, Tirtha Sarathi Ghosh Class 10 IIT Kanpur Aspirant
