i have got no numpad to draw so how do i draw then?

There's most likely the FN key that can be used to send numpad specific actions (these are usually around the U,I,O,J,K,L keys).
If you don't have that either, you can give Autohotkey a try,
You can make it send numpad 1 when pressing CTRL+1, send numpad 2 for CTRL+2, etc.
