Complex numbers: multiplication and division
Two complex numbers are given. Find their product or quotient.
Each line contains an example of multiplication or division of complex numbers. The complex number is given in the format a+bi or a-bi, where a is integer, b is non-negative integer. The real and imaginary part of each complex number is no more than
109 by absolute value.
For each input example, print in a separate line the answer.
2+3i * 7-4i 12-4i / 5-4i -1-1i * -1-1i 5-2i / -7+12i
26.00+13.00i 1.85+0.68i 0.00+2.00i -0.31-0.24i
