The addition for a abacus is very simple. Make a number, add the number of beads to your abacus, then add more beads from the next number. Here is some good examples:

  • 1+1=2
111101 110+
111101 110=
111011 110
  • 4+1=5
101111 110+
111101 110=
111110 101
  • 5+6=11
111110 101+
111101 101=
111110 011

Now these are for addition only so practice these. Even with rocks on your desk can work just as well as with a regular chinese abacus, although it may not be as fast.
