How to Calculate with Binary Numbers

Step-by-step

1. Confirm that each input contains only binary digits, 0 and 1.
2. Enter the two binary values into the calculator.
3. Choose the arithmetic operation you need.
4. Calculate the result and check its binary representation.
5. Convert the result to decimal if you need an easier cross-check.

Binary place values

From right to left, binary positions represent powers of two: 1, 2, 4, 8, 16, and so on. This place-value system is why binary values look different from their decimal equivalents.

Validate the input base

Digits such as 2 through 9 are not valid in a standard binary numeral. If your input includes them, check whether the value is actually decimal, octal, or hexadecimal.
