200 views

In binary, the negative can be represented using two's complement. To find this, invert all bits of the number (0 to 1 and 1 to 0) and add 1 to the result. This system allows for efficient arithmetic operations in computing.

FAQs & Answers

  1. What is two's complement in binary? Two's complement is a mathematical representation of negative numbers in binary, achieved by inverting the bits of a binary number and adding 1 to the least significant bit.
  2. How do you convert a binary number to its negative? To convert a binary number to its negative, you must apply the two's complement method: invert all bits (0 becomes 1 and 1 becomes 0), and then add 1 to the resulting binary number.
  3. Why is two's complement used in computing? Two's complement is widely used in computing because it simplifies the design of arithmetic circuits, allowing for efficient addition and subtraction of binary numbers.
  4. Can you represent negative numbers without two's complement in binary? Yes, other methods exist, such as signed magnitude and one's complement, but two's complement is preferred for its efficiency in arithmetic operations.
