These characteristics are true of 2's complement systems no matter how many bits there are. Let's examine a 16-bit system for comparison. We can determine that the largest positive number is 0111111111111111 which is 32,767. (An easy way to determine this is find 2¹⁵ and subtract 1.) Thus we know the smallest negative is -32,768. There are 65,536 different numbers. The largest unsigned number will be 65,535.
