Thirty-two, represented as 20 in hexadecimal, is a base-16 number system used in computing and digital electronics. In this system, the digits range from 0 to 9 and then continue with letters A to F, where A represents 10, B represents 11, and so on, up to F, which represents 15. Thus, the number 32 in decimal converts to 20 in hexadecimal. Hexadecimal is often used in programming and computer science because it simplifies binary code, making it easier for humans to read and write. Each hexadecimal digit corresponds to four binary digits (bits), allowing for a more compact representation of data.
