Introduction

Binary arithmetic is a fundamental concept in computer science, where numbers are represented using only two digits: 0 and 1. In this article, we will solve a series of binary arithmetic operations, including addition, subtraction, multiplication, and division. We will use the binary number system to perform these operations and provide step-by-step solutions.

Binary Number System

The binary number system is a base-2 number system, where each digit can have one of two values: 0 or 1. This system is used in computers to represent numbers and perform arithmetic operations. The binary number system has several advantages over the decimal number system, including:

Efficient representation: Binary numbers can be represented using fewer digits than decimal numbers, making them more efficient for computer storage and processing.
Easy to implement: Binary arithmetic operations are simple to implement in computer hardware, making them faster and more reliable.
Robustness: Binary numbers are less prone to errors and rounding issues, making them more suitable for critical applications.

Binary Arithmetic Operations

i) 11111 + 11111

To add two binary numbers, we need to align the numbers and add the corresponding digits. If the sum of two digits is 1, we write 0 and carry 1 to the next digit. If the sum of two digits is 2, we write 1 and carry 1 to the next digit.

  11111
+ 11111
------
  111110

The result of the addition is 111110.

ii) 11011 + 111

  11011
+   111
------
  10010

The result of the addition is 10010.

iii) 1101 - 11

To subtract two binary numbers, we need to borrow from the next digit if the digit we are subtracting from is 0. We also need to check if the digit we are subtracting from is greater than the digit we are subtracting.

  1101
-   11
------
   101

The result of the subtraction is 101.

iv) 1111 - 101

  1111
-  101
------
   1010

The result of the subtraction is 1010.

v) 1011 × 11

To multiply two binary numbers, we need to shift the second number to the left and add the result to the first number.

  1011
×  11
------
  11111

The result of the multiplication is 11111.

vi) 101010 ÷ 110

To divide two binary numbers, we need to shift the second number to the right and subtract the result from the first number.

  101010
÷  110
------
    101

The result of the division is 101.

vii) 11010 ÷ 10

To divide two binary numbers, we need to shift the second number to the right and subtract the result from the first number.

  11010
÷  10
------
    110

The result of the division is 110.
