Look for the command line. Out of the box it is on the bottom of the right side. When you triggered a drawing command, let's say line of two points, you are asked in the command line to specify the points. You can set these in absolute coordinates (x,y), or relative to the last point, which then is 'relative zero' and represented with that red circle. You have to set an @ in front of the coordinates (@x,y). This 'relative zero' position can also be set to your liking by the 'set relative zero position' command. You might have to set the proper snapping mode for this.
For some drawing operations an additional bar appears where you can enter values. By default it is somewhere at the top. Watch out for this.
