In this article, you can learn quickly about the Numbers Showing on Spike Abacus. You can do numbers math calculations fast with a spike abacus than normally. Showing Numbers on the Abacus benefits the children to know the numbers with their respective Place Values. Also, kids can grasp the concept of Finding out the Numbers using the Spike Abacus.

Spike abacus is a mathematical tool that might have balls with holes. Spike abacus had many iron spikes on a stiff base. You know that the abacus represents the no. of digits as spikes. The spikes are known by the places of the unit value of the digits as ones, tens, hundreds, thousands, ten thousand, etc. from right to left. Let’s discuss more information on Spike Abacus from the below modules.

## What is Spike Abacus?

An Abacus is a manual tool used to perform mathematical functions like additions, subtraction, etc. by sliding counters along with rods or grooves. Spike Abacus means the no. of multi-digits where they are shown on the spikes of the abacus. The spikes from right to left shows the place value of the digits in increasing order.

On spike abacus, we can teach the children addition, subtraction, and some other math basic concepts easily. Additions, Subtractions are the main concepts where we use them throughout our lives. Children can learn the abacus playfully. The spike abacus is considered subject to explore more calculations for students and it will be interesting to learn more through spikes.

### How to Represent Numbers in Abacus? | Representation of Numbers on Spike Abacus

The representation of Place Values in the Abacus is as follows.

**O – **ones / units

**T – **tens

**H – **hundreds

**TH – **thousands

**T-TH –** ten-thousands, etc.

With a help of an image, you can easily understand the places of the Numbers on Spike Abacus.

In the above figure, we can count the balls on the spike abacus from right to left and find the exact number **i.e.,** the number is **14213**.

### How to do Addition and Subtraction of Numbers Using Spike Abacus?

Follow the below steps for detailed information:

#### Addition using Spike Abacus

Step 1 – If we take 2-digit numbers for addition, first we have to notice the place values of the given digits.

Step 2 – Next, take the balls and keep at spikes of the abacus in one’s place of both addends as well as, take the balls and keep at spikes of the abacus in the tens place of both addends.

Step 3 – Now, add the balls on spikes in the tens place and one’s place then, you will get your addition number of given digits.

**Example:**

Add the numbers 22 + 12 using spike abacus.

**Solution:**

Given numbers are 22, 12

We have to notice the place value of the given digits.

22 – 2 balls (tens place), 2 balls (one’s place)

12 – 1 ball (tens place), 2 balls (one’s place)

Now, add the balls on spikes with their place values **i.e.,** in the tens place ( 2+1=3 spikes ), one’s place ( 2+2=4 spikes ).

Thus, the addition of given numbers is **34**.

Let’s see this example with spike abacus base

#### Subtraction using Spike Abacus

Step 1 – Subtraction is taking away from one number to the second number. If we take 3-digit numbers for subtraction.

Step 2 – First, we take away the balls on spikes from one number to the second number in one’s place and then similarly for tens place and for hundreds place.

Step 3 – Now, take the balls that remained on spikes that remained in the spike abacus base. The left balls on spikes are our subtracted number of given digits.

**Example:**

Subtract 432, 321 using spike abacus.

**Solution:**

Given numbers are 432, 321

We have to take away from one number to the second number with their respective place values.

So, we take away 2 balls from 1 ball of one’s place digits and left with 1 ball on the spike of one’s place.

Similarly, 3 balls from 2 balls of tens place and left with 1 ball on the spike of tens place. 4 balls from 3 balls of hundreds place are left with 1 ball on the spike of hundreds place.

Thus, the subtracted number is **11****1**.

Let’s see this subtraction using spike abacus base

#### Reasons to Use Spike Abacus

- Improves concentration level
- Increase Accuracy while solving
- Boosts confidence in students
- Improves brain power and visualization
- Enhances your observation of things

#### FAQs on Numbers Showing on Abacus

**1. What does Abacus mean?**

An Abacus is a device that helps kids to calculate math calculations by using the beads that moved up and down on a sequence of sticks or spikes inside a wooden frame.

**2. How to write a number in spike abacus?**

In order to write a number in the spike abacus, first, check the place values of the given digits and use the required beads in the respective place values and then calculate the math functions using the abacus.

**3. How to show the number 25 in the abacus?**

To show number 25 in the abacus, initially take the 5 which is in one’s place and keep five balls or beads in one’s place spike then 2 which is in the tens place so keep two beads in ten’s place spike. Then, see the beads in both the place values you get the number 25 on the spike abacus base.
