Interpret 11011011 as a two's complement binary number, and give its decimal equivalent. First, note that the number is negative, since it starts with a 1. Change the sign to get the magnitude of the number. Convert the magnitude to decimal: 001001012 = 2516 = 2Ã16 + 5 = 3710.
1032 is equal to 1Ã1000 + 0Ã100 + 3Ã10 + 2Ã1. By writing numbers in this form, the value of each column becomes clear. The binary number system works in the exact same way as the decimal system, except that it contains only two digits, 0 and 1. Start counting in binary: 0, 1, Oops! There are no more binary digits. In order to keep counting, we need to add a second column worth twice the value of the column before.
