    This set would be represented by, let it be called set A, then, A= {0, 1, 2, 3, 4}

    Is it clear to you??? I hope you have no doubts... If you have any, you can discuss.

    they used to call the list of names that the teacher would call at the start of class a "roster". Roster form is simply naming all the elements one by one; or using the ... as needed

    set builder notation uses "equations" or inequations to define the set and can involve "ors" and "ands"

    Okay, then the exact solution would go like this- Roster form shows all the elements of the set , in curly brackets, A= {0,1,2,3,4} Set Builder form depicts the properties defining the elements of the set, A= {x: \[ 4 \ge x \ge0\] and \[xin\mathbb{N}\]

    Sorry , latex error, this "in" signifies "belongs to"

    What are the solutions of : e. 2(t -1) + 3t < 2 f. 4n +2 < 7(n – 13) g. 14 – 6n ≤ 2 (7-3n) h. 4p + 3 > 9p +6 -5p

    Check the first one, simplify by opening braces, 2t - 2 + 3t < 2 i.e., 2t + 3t < 4 i.e., 5t < 4 which gives t < 4/5 t∈(-∞,4/5) gives us the solution set...

    Be careful about using Round braces (.) or Square braces [.] because they have different meanings, (.) signify that the end points are NOT included, and [.] signify they are contained , like above , infinity and 4/5 are NOT contained, ( INFINITY CAN NEVER BE CONTAINED IN A SET)

    But she is NOT replying to my posts, and further this is an example, intended to be used for other parts by herself... Even I am not good at typing much..
