Answer 1

- A Set-builder notation is used to express the solution set of an inequality. It uses brackets and a vertical bar to indicate the solutions.

- For example, the set of even numbers between 1 and 10 exclusive, is:

`\lbrace x|x:2,4,6,8\rbrace`

- As we can see the set above has a bracket and it also has a vertical bar as well.
