To quickly assess the difficulty of the text, read a short excerpt:
We have seen (§ 188) the two-dimensional nature of complex number, and the infinite variety of ways in which it may vary continuously from a -\- hi to c -f di, because the protomonic and neomonic parts may vary independently. In order that x -\- yl shall become zero, x and y must vanish simultaneously. Por, li x -\- yi = 0, ic = — yi, and hence cc = and y = 0, — else would a protomonic number equal a neomonic, Avhich is impossible except both be zero. (Vide § 183. ) On the other hand, if either... x or y becomes infinite, x -{- yi=cc. (FicZe§198). 120 NUMBER AND ITS ALGEBRA. 194. Li a -\- bi = G -\- di, then a = c and b = d. For, subtracting c -f- di from each member of the given equation, a — c-\-(b — d)i = 0; therefore, by Section 193, d — c = and b — d ^= ; that is, a = c and b = d. Of course, since x + (— y) = x — (+ y) ox x — y {% 120), the preceding formula inckides all combinations as a, b, c, and d are positive or negative ; e. G. , if a -f bi = c — di, a = c, b = — d.
