The Binary Calculator performs both arithmetic operations (add, subtract, multiply, divide) and bitwise operations (AND, OR, XOR, NOT, shift left, shift right) on numbers in any base. You can mix bases — for example, add a binary number to a hexadecimal number. The result is displayed in all four bases simultaneously for easy reference.

Bitwise operations work on the individual bits of numbers. AND returns 1 only where both inputs have 1. OR returns 1 where either input has 1. XOR returns 1 where inputs differ. NOT flips all bits. Shift left (<<) multiplies by 2 for each position, while shift right (>>) divides by 2. These operations are fundamental in programming, networking, and computer science.
