- Finally, it’s worth noting that arithmetic operations are not just important for computer programs themselves, but also for the people who use them. Whether we’re using a calculator to check our math homework, or a spreadsheet to track our finances, arithmetic operations are an essential part of our daily lives.

### The Basics of Arithmetic Operations

Arithmetic operations are fundamental mathematical operations that involve numbers. These operations include addition, subtraction, multiplication, and division. They are used to manipulate numbers and perform calculations.

In a computer system, numbers are represented using binary code. Binary code is a series of 0s and 1s that represent different numerical values. The computer uses these binary values to perform arithmetic operations.

To perform arithmetic operations, the CPU follows a series of steps. First, it retrieves the numbers to be operated upon from memory. Then, it performs the desired operation, such as addition or multiplication, using binary code. Finally, the result is stored back into memory.

It is important to note that computers can only perform arithmetic operations on whole numbers. They cannot perform operations on fractions or decimals. To perform calculations with fractions or decimals, computers use algorithms that approximate the values as whole numbers.

In summary, arithmetic operations are essential to computer systems. They allow computers to perform calculations and manipulate numerical data. The CPU uses binary code to perform these operations and retrieve the results.
