If a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of X is 1, find a + B + X + CD of X

If a and B are opposite to each other, C and D are reciprocal to each other, and the absolute value of X is 1, find a + B + X + CD of X

a. B is opposite to each other, so a + B = 0
c. D is reciprocal to each other, so c * d = 1
The absolute value of X is 1, so / X / = 1. So x = 1 or x = - 1
A + B + X + CD of X
=0 + 1 + 1 / x = 2 or
=0-1+1/-1=0
