Calculate Logical OR Operation

Example Calculation

Binary OR Example

Number 1: 10110 (binary) = 22 (decimal)

Number 2: 11101 (binary) = 29 (decimal)

Operation: 10110 OR 11101

Step-by-Step Solution

10110

OR 11101

-------

11111

Result: 11111 (binary) = 31 (decimal)

OR Truth Table

ABA OR B
000
011
101
111

The OR operation returns 1 if either input is 1, and 0 only when both inputs are 0.

OR Gate Symbol

ABQ

Standard OR gate symbol in digital logic

OR Operation Properties

Commutative: A OR B = B OR A

Associative: (A OR B) OR C = A OR (B OR C)

Identity: A OR 0 = A

Idempotent: A OR A = A

Annihilator: A OR 1 = 1

Understanding the Logical OR Operation

What is the Logical OR?

The logical OR is a fundamental boolean operation that performs an inclusive disjunction between two or more operands. The result is true (1) when at least one of the operands is true (1), and false (0) only when all operands are false (0).

Applications

  • Digital circuit design and logic gates
  • Computer programming and conditional statements
  • Boolean algebra and mathematical logic
  • Database queries and search operations

How to Calculate Bitwise OR

  1. 1. Align the binary numbers from right to left
  2. 2. Compare each bit position
  3. 3. Apply OR logic: 0 OR 0 = 0, all other combinations = 1
  4. 4. Write the result bit in the corresponding position
  5. 5. Continue for all bit positions

Symbols and Notation

  • Logic: A ∨ B
  • Programming: A || B (logical), A | B (bitwise)
  • Electronics: A + B
  • Boolean algebra: A + B
