ANSWER:
ROASTER FORM:
It is difficult to express a set in a long sentence.thats why ,generally sets can be denoted by capital letters of English alphabets.
for example,M is a set of molars among our teeth.
we can write as M= {first molar,second molar,third molar}
-------------------------------
SET BUILDER FORM
for example,
A=(x:x is a multiple of 3,x<20)
we read as "A is a set of elements x such that x is a multiple of 3 and x is less than 20"
