9 half adders are sufficient..

since LSB addition has implicit carry=0, which can be done using one half adder, rest 4 bits require full adders and each full adder can be made with 2 half adders,

in total 1+ 4*2 = 9 half adders are required
CAN U DRAW CIRCUIT DIAGRAM?

AND WHAT ABOUT TO IMPLEMENT HALF SUB WITH MUX

I THINK ANSWER IS 2?
