The absolute value of the number 5 is 5, which is itself; the absolute value of the number - 5 is 5, which is its opposite number; the above comes from the theorem that the absolute value of a non negative number equals itself, and the absolute value of a non positive number equals its opposite number______ The absolute value of negative number - B is______ The absolute value of negative number 1 + A is______ The absolute value of positive number - A + 1______ ．

The absolute value of the number 5 is 5, which is itself; the absolute value of the number - 5 is 5, which is its opposite number; the above comes from the theorem that the absolute value of a non negative number equals itself, and the absolute value of a non positive number equals its opposite number______ The absolute value of negative number - B is______ The absolute value of negative number 1 + A is______ The absolute value of positive number - A + 1______ ．

The absolute value of a negative number is equal to its opposite number; the absolute value of zero is equal to 0; the absolute value of a positive number is itself. Therefore, the answer is: - A; B; - 1-A; - A + 1
