Representation of Numbers on the Abacus
We will learn representation of numbers on the abacus.
Numbers on Abacus:
|
This abacus is having two spikes. Spike on the left is Tens spike and spike on the right is Ones spike. |
The number of beads placed in Ones spike reads Ones number and the number of beads in Tens spike reads Tens number.
|
Showing 1 at Ones place and 0 at Tens place. So, the number is 0 Tens and 1 Ones - 1 Therefore, it is showing the number 1. |
|
Showing 0 at Ones place and 1 at Terns place. So, the number is One Tens and 0 Ones - 10 Therefore, it is showing the number 10. |
We can show 100 on an abacus with three vertical rods. The rods represent place value of hundreds, tens and ones. We add beads on the rods to show different number. Each rod can hold up to 9 beads.
 This shows 9 ones |
 If we add 1 more to 9 it is 10 ones. Regroup 10 ones as 1 ten. |
 This shows 9 tens and 9 ones. The number is 99. |
 If we add 1 more to 99 it is 10 tens. Regroup 10 tens as 1 hundred. |
1 bead in the hundreds place represents 1 hundred.
To read a 3-digit number first read the hundreds place and then the last two digits place.
Let us take this example:
|
5 beads in the hundreds place means 5 hundreds. 4 beads in the tens place means 4 tens. 2 beads in the ones place means 2 ones.
The number can be written as 542 = 5 hundreds 4 tens and 2 ones Five hundred forty-two |
