Stmt1.

Distance between S and 0 is same as distance between 0 and T.

distance is the absolute value of the imaginary number. Lets say distance = 3 units. Therefore S will 3 and t = -3 or vice versa. S and T are the positive and negatives of the same imaginary number.
hence S + T = 0

sueff

Stmt2

0 between S at T. but then there are infinite +ve and -ve numbers on either side of 0. Not sueff.
