单词	addition
释义	addition (of complex numbers) Let the complex numbers z1 and z2, where z1 = a + bi and z2 = c + di, be represented by the points P1 and P2 in the complex plane. Then z1 + z2=(a + c) + (b + d)i, and z1 + z2 is represented in the complex plane by the point Q such that OP1QP2 is a parallelogram; that is, such that . In this way the addition of complex numbers corresponds exactly to the addition of vectors. The parallelogram OP1QP2
