we see the whole numbers 1 through 12

Answer 2

when they say to list the elements in roster form, they just want you to list out EVERY element

in this case, just the two digit numbers

so we just write \(\LARGE \{10, 11, 12\}\)

Answer 3

don't forget to write the curly braces so the teacher knows that you're indicating a set of values
