left parenthesis negative straight A right parenthesis space means space the space negative space of space straight a space matrix space straight A. Thus comma space if space matrix space straight A equals open square brackets table row 7 cell negative 3 end cell 4 row cell negative 2 end cell 5 cell negative 1 end cell end table close square brackets comma space then space minus straight A equals open square brackets table row cell negative 7 end cell 3 cell negative 4 end cell row 2 cell negative 5 end cell 1 end table close square brackets
