How does the two’s-complement scheme address the shortcomings of sign-magnitude representation?
Stephen Davies, Ph.D. Version 2.2.2 Through Discrete Mathematics A Cool Brisk Walk / Chapter 1
"Two’s-complement This shortcoming in the sign-magnitude scheme is remedied with the two’s-complement scheme, which is the one actually used most often in practice. It’ll seem weird at first — certainly not as intuitive as the first two — but it leads to a critically important feature that we’ll look at shortly. First, the rules. To interpret a two’s-complement number, you:"
