It would be good if you try design and code by yourself first and then see other's code

Hi

module add3(in,out);
input [3:0] in;
output [3:0] out;
reg [3:0] out;
always @ (in)
case (in)
4'b0000: out <= 4'b0000;
4'b0001: out <= 4'b0001;
4'b0010: out <= 4'b0010;
4'b0011: out <= 4'b0011;
4'b0100: out <= 4'b0100;
4'b0101: out <= 4'b1000;
4'b0110: out <= 4'b1001;
4'b0111: out <= 4'b1010;
4'b1000: out <= 4'b1011;
4'b1001: out <= 4'b1100;
default: out <= 4'b0000;
endcase
endmodule
