Introduction

Binary numbers are the foundation of computer science, and understanding how to perform arithmetic operations on them is crucial for any aspiring programmer or computer scientist. In this article, we will delve into the world of binary subtraction, exploring the process of subtracting two binary numbers, specifically 1101011 and 111010.

What is Binary Subtraction?

Binary subtraction is the process of subtracting one binary number from another. It is a fundamental operation in computer arithmetic, and it is used extensively in various applications, including computer programming, digital electronics, and data processing.

Binary Number Representation

Before we proceed with the subtraction, let's briefly review the binary number representation. Binary numbers are represented using only two digits: 0 and 1. Each digit in a binary number is called a bit. The position of each bit represents a power of 2, starting from the right (2^0, 2^1, 2^2, and so on).

Binary Subtraction Process

The binary subtraction process involves borrowing from the next higher place value when the digit in the current place value is less than the digit being subtracted. Here's a step-by-step guide to the binary subtraction process:

Compare the two binary numbers, starting from the rightmost digit.
If the digit in the current place value of the first number is greater than or equal to the digit in the same place value of the second number, subtract the two digits and write the result in the same place value.
If the digit in the current place value of the first number is less than the digit in the same place value of the second number, borrow 1 from the next higher place value and subtract the two digits. Write the result in the same place value.
Repeat steps 2 and 3 for each place value, moving from right to left.

Subtracting 1101011 and 111010

Now that we have a good understanding of the binary subtraction process, let's apply it to the given numbers: 1101011 and 111010.

Step 1: Compare the Rightmost Digits

The rightmost digits of the two numbers are 1 and 0, respectively. Since 1 is greater than 0, we subtract 1 from 1 and write the result in the same place value.

Step 2: Compare the Next Higher Place Value

The next higher place value is 2^4 (16). The digit in the same place value of the first number is 0, and the digit in the same place value of the second number is 1. Since 0 is less than 1, we borrow 1 from the next higher place value (2^5 or 32) and subtract 1 from 0. This gives us a result of 1 in the same place value.

Step 3: Compare the Next Higher Place Value

The next higher place value is 2^5 (32). The digit in the same place value of the first number is 1, and the digit in the same place value of the second number is 1. Since 1 is equal to 1, we subtract 1 from 1 and write the result in the same place value.

Step 4: Compare the Next Higher Place Value

The next higher place value is 2^6 (64). The digit in the same place value of the first number is 1, and the digit in the same place value of the second number is 0. Since 1 is greater than 0, we subtract 1 from 1 and write the result in the same place value.

Step 5: Compare the Next Higher Place Value

The next higher place value is 2^7 (128). The digit in the same place value of the first number is 0, and the digit in the same place value of the second number is 1. Since 0 is less than 1, we borrow 1 from the next higher place value (2^8 or 256) and subtract 1 from 0. This gives us a result of 1 in the same place value.

Step 6: Compare the Next Higher Place Value

The next higher place value is 2^8 (256). The digit in the same place value of the first number is 1, and the digit in the same place value of the second number is 0. Since 1 is greater than 0, we subtract 1 from 1 and write the result in the same place value.

Step 7: Compare the Next Higher Place Value

The next higher place value is 2^9 (512). The digit in the same place value of the first number is 1, and the digit in the same place value of the second number is 0. Since 1 is greater than 0, we subtract 1 from 1 and write the result in the same place value.

Step 8: Compare the Next Higher Place Value

The next higher place value is 2^10 (1024). The digit in the same place value of the first number is 0, and the digit in the same place value of the second number is 0. Since 0 is equal to 0, we subtract 0 from 0 and write the result in the same place value.

Conclusion

In conclusion, subtracting 1101011 and 111010 in binary number results in 0011111. This process involves borrowing from the next higher place value when the digit in the current place value is less than the digit being subtracted. Understanding binary subtraction is crucial for any aspiring programmer or computer scientist, and it is used extensively in various applications.
