**Numbers on Abacus:**

This abacus is having two spikes. Spike on the left is Tens spike and spike on the correct is Ones spike. |

The variety of beads positioned in Ones spike reads Ones quantity and the variety of beads in Tens spike reads Tens quantity.

Displaying 1 at Ones place and 0 at Tens place. So, the quantity is 0 Tens and 1 Ones – 1 Due to this fact, it’s displaying the number one. |

Displaying 0 at Ones place and 1 at Terns place. So, the quantity is One Tens and 0 Ones – 10 Due to this fact, it’s displaying the quantity 10. |

We will present 100 on an abacus with three vertical rods. The rods characterize place worth of a whole bunch, tens and ones. We add beads on the rods to indicate completely different quantity. Every rod can maintain as much as 9 beads.
