need help to design calculator function (addition and multiplication)

hi,hamema.

I will tell you two things.

one is 7segLED.

see attached file.

a means LED's 0 pin

b means LED's 1 pin

....

g means LED's 6 pin

the dot means LED's 7 pin

the second thing is...

just use case sentence.

when you get value "0"

set each pin like that.

------------------ verilog HDL logic -------------------

case ( outadd )

0:

begin

a = 0;//(negative logic )

b = 0;

c = 0;

d = 0;

e = 0;

f = 0;

g = 1;

dot = 1; //whatever

end

1:

begin

a = 1;

....

endcase
