When multiplying a negative number written using the one's complement convention, 1, and not 0, should be inserted into the LSB. A clear example of this is 1101 (-2). When left-shifted as described in the article, it'd become 1010 (-5). However, if 1 is put into the LSB, it becomes 1011(-4), the correct answer. So actually, when using one's complement, the signal bit should be reinserted into the LSB after the shift. Budsbd 14:30, 6 March 2007 (UTC)
