1 Digit Number on Spike Abacus

1 Digit Number on Spike Abacus | Representation of 1-Digit Numbers using Abacus

Students who are excited to learn abacus should start with fundamentals like representing numbers on Spike Abacus. In the abacus, the numbers are shown by the place value of the digits like one’s, tens, hundreds, and so on.

Now, we will start with learning how to write 1-digit numbers on a spike abacus, which helps the children to know about the concept of numbers. In this guide, you get to know about the detailed information on showing a 1-digit number on Abacus. If you want to check how to represent the numbers on the spike abacus in a detailed way, let’s click on the direct link provided here.

What are One-Digit Numbers?

As we know the smallest and greatest 1-digit numbers are 1 & 9. To find the list of 1-digit numbers subtract the greatest from the smallest 1-digit number i.e., 9 – 1 = 8. Now, add 1 to the respective result so that you get to know how many 1-digit numbers are there i.e., 8+1=9.

The list of 1-digit numbers is 1, 2, 3, 4, 5, 6, 7, 8, 9. Let’s discuss how these 1-digit numbers are represented in spike abacus using beads. All one-digit numbers are placed in the one’s place spike of the spike abacus base. Below, we are going to show how to represent 1-9 numbers using a spike abacus.

The represented balls in one’s spike are considered as one-digit numbers. For example, if the number is 5 then you will see the 5 beads on the one’s place of spike abacus. For quick reference and easy memorization, we have given 1 to 9 numbers representation on the spike abacus via images.

1-Digit Numbers Representation on Spike Abacus Examples

Example 1:

Add the numbers 4 and 3 using spike abacus?

Solution:

Given numbers are 4 and 3

For adding 1-digit numbers on the spike abacus, you should follow the below steps carefully,

In step 1, we have to represent the first given 1 digit number in the abacus ie., 4 beads in one’s place spike on the abacus.

In step 2, take another given digit number ie., 3, and place the 3 beads in one’s place spike on the abacus.

Now, add one’s place beads of two spikes to get the final result of adding 4 and 3 (1-digit numbers) using spike abacus.

ie., 4 + 3 = 7.

Thus, is the answer.

Below is the representation of the addition of numbers 4, 3 using spike abacus base:

Example 2:

Subtract 1-digit numbers 5, 2 using spike abacus?

Solution:

Given numbers are 5, 2

Follow, the below steps to subtract the given numbers using spike abacus:

First, we have to place these numbers as beads on one’s place on the abacus base.

ie., 5 beads on one’s place of the first spike, and then 2 beads on one’s place of another spike.

Subtract these beads from one spike to another spike then you will get the subtracted one-digit number.

Subtraction is 5 – 2 = 3. Thus, is the answer.

Let see this subtraction using Spike Abacus as below:
