#2/ Prime Number - A natural number greater than 1 which has only 1 and itself as factors. P=2,3,5,7,11,13,17,… #3/ Composite Number - A natural number greater than 1 which has more factors than 1 and itself., 4,6,8,9,10,12,....

#4/ Whole Numbers - The set of Natural Numbers with the number 0 adjoined. W=0,1,2,3,4,… #5/ Integers - Whole Numbers with their opposites (negative numbers) adjoined. Z =…,−3,−2,−1,0,1,2,3 ,… #6/ Rational Numbers - All numbers which can be written as fractions. Q= 4 ,- 5 −12,0.33333…,52,1110, 6 10.

#7/ Irrational Numbers - All numbers which cannot be written as fractions. F =...,π,2–√,0.121221222 ... #8/ Real Numbers - The set of Rational Numbers with the set of Irrational Numbers adjoined. R =...,−3,−1,0,15,1.1,2–√,2,3,π,.

#9/ Complex Number - Numbers other than real numbers are imaginary or complex numbers. It can be written in the form a + bi where a and b are real numbers and i is the square root of -1. C =...,−3+2i,0,1+3i ,… Let me give you more words on this part. For eg , √1=1 √ - 1 = i If its √ -4 = 2 i The imaginary number, √− 64 , is equal to 8i ..
