Each part of the first complex number gets multiplied by each part of the second complex numberJust use "FOIL", which stands for "Firsts, Outers, Inners, Lasts" (see Binomial Multiplication for more details):Firsts: a× c Outers: a× di Inners: bi × c Lasts: bi × di (a+bi)...
Then, if we do multiplication of a purely imaginary number of the form bi with a complex number, then the formula becomes (bi) (c + id) = ibc – bd. For example, if we multiply a complex number 2 + 3i with -5i, we have: (-5i) (2 + 3i) = -10i -15i2 = -10i + 15 ...

A complex number is a number which has two distinct parts: a real part and an imaginary part. Geometric representation of a complex number in Cartesian and polar form. The imaginary part of a complex number relies on the multiplication of a real number with an imaginary number (usually a "...
A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, that satisfies the equation x2 = −1, that is, i2 = −1.[1] In this expression, a is ...
3. Show that the final formula for division follows from the definition of multiplication (as it should): if z = z1/z2 then z1 = zz2, solve for (z) and (z).1.2 Limits and DerivativesThe modulus allows the definition of distance and limit. The distance between two complex numbers z...
A complex number z=a+bi can be identified with a point( or vector) (a,b) on the Cartesian plane. Algebraic on complex numbers Let z=a+bi , w=c+di Addition: z+w=(a+c)+(b+d)i Subtraction: z−w=(a−c)+(b−d) Multiplication: zw=(ac−bd)+(ad+bc)i Complex ...
