If AB is opposite to each other and CD is reciprocal to each other, then the algebraic formula (a + b) & # 178; - (CD) is 1 / 100

If AB is opposite to each other and CD is reciprocal to each other, then the algebraic formula (a + b) & # 178; - (CD) is 1 / 100

That is, a + B = 0
cd=1
So the original formula = 0 / 100 & # 178; - 1 / 1
=0-1
=-1
