Question

A={4,6,9,11,14 }. Determine whether the statements are true or false.

a) { 4,9,14} belongs to A

Answer 1

and why , I have the answer but I don't get it.

Answer 2

belongs to A or is a subset of A?

Answer 3

it is a subset for sure, but it does not belong to A
those are two different things

Answer 4

for example \(\{1,2,3\}\) is a subset of all positive whole numbers, but \(\{1,2,3\}\) is not a whole number

Answer 5

so \(\{4,9,14\}\in A\) is not correct, but
\[\{4,9,14\}\subset A\] is correct

Answer 6

`\(\in\)` makes \(\in\)
