by the procedure design a half subtractor
design a logic ciruit to add two numbers with five bits each

To make a full subtractor, you need an XOR and a NAND gate.
THE MAIN ADVANTAGE OF THE UNIVERSAL LOGIC GATES IS THAT IT CAN BE USED TO MADE ANT KIND OF LOGIC GATE .......BY USING IT . NAND AND NOR ARE CALLED AS UNIVERSAL GATES ARE USED TO MAKE ANY GAATES AS OR ,AND, XNOR,NOT. logic gates are used in many everyday electronic devices such as tv's, computers and telephones.
because it is an universal gate that control and repairs other gates.
A "Nand" gate is an "And" gate with an "Inverter" added to its output. To get a logic 1 output from a "Nand" gate, you need a logic 0 on both of its inputs. If I understand your question correctly, you have three "Nand" gates. Presumably the outputs of two of them are connected to the inputs of the third. Logic 1 at both inputs of the first two "Nand" gates will produce a logic 0 output from both of them. The two logic 0's are fed to the inputs of the third "Nand" gate producing a logic 0 output from the third "Nand" gate.
That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.

You cannot design a full adder using only OR gates. You also need AND gates. Typically, this can be done with just NAND gates.

9,to implement a half adder 5 nand gates and for a full adder,another xor gate is required consisting of 4 nand gates. thus a total of 9 nand gates are required for a full adder.
The combinational logic circuits are a type of logic circuits containing only logic gates (AND, OR, XOR, NOT, NAND, NOR) and its output only depends on the current input (do not have memory).
universal logic gate is a gate using which you can make all the logic gates there are two such gates NOR gate and NAND gate
many inputs one outputs
nand gate
Not And (electronic logic gate)
Final answer will be NAND bz from first NAND ans NOT AND then Again NOT ( NOT AND) ans AND then Again NOT ( AND) so final ans will be NAND.
