Online Binary Calculator
Our Binary Calculator allows you to perform all basic arithmetic operations with binary numbers, including addition, subtraction, multiplication, and division. Whether you are a student learning digital logic or a programmer working on low-level code, this tool provides instant and accurate results for any base-2 calculations.
Binary Arithmetic Examples
How to add binary numbers (1011 + 1101)?
Result: 11000
Step-by-step:
1. 1 + 1 = 10 (write 0, carry 1).
2. 1 + 0 + 1 (carry) = 10 (write 0, carry 1).
3. 0 + 1 + 1 (carry) = 10 (write 0, carry 1).
4. 1 + 1 + 1 (carry) = 11. Final result: 11000.
Binary Subtraction (1110 — 101)
Result: 1001
How to calculate: Align the bits. Since 0 — 1 requires a borrow, you take from the next bit. 14 (decimal) — 5 (decimal) = 9, which is 1001 in binary.
Binary Multiplication (101 x 11)
Result: 1111
Logic: Multiply 101 by the first ‘1’ (101), then by the second ‘1’ shifted left (1010). Summing 101 + 1010 gives 1111 (15 in decimal).

Rules & Logic Guide
The binary system, or base-2, is the fundamental language of modern computing. Unlike the decimal system (base-10), which uses ten digits, binary uses only 0 and 1. Every piece of data, from high-definition video to simple text, is processed by computers as a sequence of these bits.
Fundamental Rules of Binary Operations
When using our binary solver, it helps to understand the underlying logic used for bitwise operations:
- Addition Rules: 0+0=0, 0+1=1, 1+0=1, and 1+1=10 (this means 0 in the current column and a «carry» of 1 to the next).
- Subtraction Rules: 1-1=0, 1-0=1, 0-0=0, and 0-1=1 (this requires a «borrow» from the higher-order bit).
- Multiplication: Identical to decimal long multiplication: 0×0=0, 0×1=0, 1×1=1.
- Division: Calculated through a series of subtractions and shifts, much like long division in decimal math.
Why Use an Online Binary Calculator?
Manually calculating long binary strings is prone to errors, especially with carry-overs and borrows. Our tool is essential for:
- Computer Science Students: Perfect for verifying homework on logic gates and machine architecture.
- IT Professionals: Useful for network subnetting and bitwise programming tasks.
- Engineers: Essential for designing digital circuits where transistors operate in binary states.

Verification and Conversion
To verify any binary result, you can convert the numbers to decimal, perform the math, and convert the result back. For a deep dive into the history of the base-2 system, you can check the resource on Wikipedia.
