Calculate directly with binary integers
The binary calculator page lets you add, subtract, multiply, divide, and take remainders without first converting bit strings by hand. It is useful for digital logic exercises, flag checks, and quick verification when binary is the format you are already using.
Enter two binary integers and choose an operation. The result is shown in binary first, with decimal and hexadecimal rows underneath so you can cross-check the same value in more familiar or compact notation.
How to use the binary calculator
- Enter the first binary value using only 0 and 1.
- Enter the second binary value.
- Select add, subtract, multiply, divide, or modulo.
- Use the decimal result to confirm the arithmetic if the binary result is long.
- Use the hexadecimal result when the answer needs to fit code or documentation.
Binary calculator examples
| Input | Result | Why it matters |
|---|---|---|
1010 + 11 |
1101 |
Ten plus three equals thirteen. |
1111 - 1 |
1110 |
A simple subtraction from fifteen. |
1000 * 10 |
10000 |
Eight times two equals sixteen. |
Binary calculator input rules
Both operands must be binary integers. Values containing 2 through 9 or A through F are rejected because they belong to other bases.
Division and modulo use integer arithmetic and require a nonzero second operand. That matches the whole-number nature of bit patterns and masks.
How binary arithmetic is shown
The calculator converts each operand to an exact integer, performs the selected operation, and formats the result back to binary. Decimal and hex rows come from the same result.
Binary carries happen when a column reaches two. For example, 1 + 1 becomes 10 in binary, just as 9 + 1 becomes 10 in decimal.
Good uses for binary arithmetic
- Checking homework or digital logic examples.
- Adding or subtracting small bit patterns.
- Comparing binary math with a decimal explanation.
- Verifying mask operations before writing documentation.
Accuracy notes
This is an integer calculator, not a bitwise operator panel. It performs arithmetic operations, so it does not replace AND, OR, XOR, or shift tools.
The calculator does not infer fixed-width overflow. If your target wraps at a certain number of bits, apply that rule separately.

Keeping each page centered on one core task makes the tool faster to use and makes the explanation easier to follow.
Frequently asked questions
Can I use 0b prefixes?
For calculator fields, enter the binary digits directly for the clearest validation.
Does division return a remainder?
Division returns the quotient. Use modulo to get the remainder.
Does it support bitwise AND or XOR?
No. This calculator focuses on arithmetic operations.
