Chapter definitions. A complex number is the first pair (a, b) when a and b are real numbers. And the same schedule. Addition and multiplication of complex numbers, as follows: For complex numbers (a, b) and (c, d) 1. the equal (a, b) = (c, d) If a = c and b = d. 2. Add (a, b) + (c, d) = (a + c, b + d) 3. multiply (a, b): (c, d) = (ac-bd, ad-bc) Maybe instead of (a, b): (c, d) with (a, b) and (c, d) it. The set of complex numbers with symbols rather than written C.
