The following is a nested enumerate environment

A. This is the first irem

B. This is the second item

C. (a) This is the sub item one

(b) This is the sub item two

(c) i. This is the subsub item one

ii. This is the subsub item two

(d) this is the sub item three

D. This is the third item

* This is the first irem

* This is the second item

* + This is the sub item one

+ This is the sub item two

+ , This is the subsub item one

, This is the subsub item two

+ this is the sub item three

* This is the third item

Complex Numbers The numbers of the form z = a + ib, where a and b arereal numbers and i2 = 1 are called Complex numbers. a is called thereal part and b is called the imaginary part of the complex number.

Conjugate For a complex number z = a + ib, the complex conjugate of z isdefined as z = a ib

Modulus Let z = a + ib is a complex number then we can assume z as thepoint (a, b) in the two diamentional plane, then the distance from (a, b) tothe origin is called the modulus of the complex number
