How to display numbers

Here is an easy way to clear the Soroban/Abacus and make it show zero before operations.

  • Before starting to calculate on the Soroban/Abacus, hold the Soroban/Abacus with the left hand on the left hand side of the Soroban/Abacus, if you are right-handed, and the opposite way if you are left-handed.
  • Gently lay the Soroban/Abacus down flat on the desk.
  • Move your right forefinger from left to right along the upper edge of the bar gently pushing the 5 beads with your forefinger finger nail. This will push up all the top beads. When all the top beads are up and all the bottom beads are down, the Soroban/Abacus shows zero.
  • Look at the images below. These show you the numbers 1 to 9 as they would appear on a Soroban/Abacus.
