The basic computer Operation is the operation that is accomplished in a given task like taking the input to store to process and finally giving the output.

There are the five basic computer operations that are :-

**Input**– taken the data as a command

**Storage-** Store the input in memory

**Process-** process the store input in memory

**Control-** control all the requests while processing

**Output- **finally with help of all the control the process input data and acquiring the output.

While processing this operation some are the operations that are used to operate the arithmetic operation like adding, subtraction, multiplication, etc.

To elaborate **arithmetic operations – subtraction** –

Firstly, we will learn

**What is the arithmetic operation?**

Arithmetic operation is a function that takes two operands and performs a calculation on them.

The computer uses different symbols for calculation purposes.

Like subtraction (-)

Addition (+)

Multiplication (*)

Division (/)

**What is the Arithmetic operation of subtraction?**

The arithmetic operation is the operation in that operands on two modules and subtraction or casement occur and the result will show. All these operations are performed in the memory of the computer where the operand or module is stored. And the **arithmetic operation – subtraction** performed in the memory only and the result will show.

**The process of the arithmetic operation of subtraction in basic computer operation –**

Firstly it will take the two operands of two modules to take as input then the inner system store in the memory and assign the memory address to the one operand and the second operand and the third is for the resultant operand. Then the process function process the **arithmetic operation-subtraction** on the stored operating and shows the result to the given resultant address

The output field shows the result which occurred during the processing by fetching the resulting data into the storage location.

Lastly, during all of the processing, the controller of the computer means the CPU controls all these activities.

All this process is completed in a nanosecond.

**Example of Arithmetic operation-subtraction**

Subtraction means or used when to find what is left out when things are taken out

For example, the total no of apples is 20 in the basket and 5 apples are been given to the needy people how many apples are remaining in the basket

We will find the answer with the help of the arithmetic operator that is 20-5=15.

This is a simple language to calculate the solution now but the question is how it will take on the computer.

In a computer, the process is the same while processing the solution in the normal way on pen and paper.

But the difference is that we have to write a question then count down what is left from the number. But on the computer there is no count , no mindset problem. Only of the remember is two operands and arithmetic operation function. That’s all the result will be on the screen.

**Why is Arithmetic operation-subtraction a part of a computer subject?**

As per the study or our childhood study the arithmetic comes in the mathematical function or the category of maths subject but our computer is a machine which takes data as input and gives out the result as an output while performing these actions some seconds are taken. As compared to the normal human mindset.So that is why the Arithmetic operation -subtraction is the part of the computer system as these perform operands in nanoseconds.

**Importance and order of Arithmetic Operation-Subtraction**

Subtraction is the most significant tool that helps us to recognize what is resting when picking up one number left from another number. For example, if Senorita has $25 and she spends $15 on the new skirt, we could use subtraction to recognize how much rupees Senorita has spent.

**Rules of Subtraction Operation**

- First of all, maintain the number
- Then, we need to place the operator of subtraction.
- Then insert another number that needs to be subtracted from the first number.
- At the end, we will get the result of the subtraction.

**Conclusion**

We observe that or we understand that arithmetic operations are the operation of the mathematical performers who perform the mathematical operations as a means of function.

Some of the main operations of thematic operation are addition, subtraction, multiplication, division.

Whereas subtraction is an arithmetical operation that performs the subtraction function on the two operands. All these functions or operations are the basic operation of the computer only.

All of the categories are used for time management to crack the competitive exam like state level and nation wise for example- NDA, SSC, etc.
