Based on personal experience my answer to this question is, to study more.

If You walk into a test,

and You know all of the topics,

and have worked through all of the types of questions You need to know,

Then nothing else matters and You walk in there like a BOSS!!!

On top of that, if You are worried about the social pressures from the people around You, Consider how Einstein might have felt when he walked into an examination in his earlier days.

Or another person that You regard highly. Feel connected to these people, and respect Yourself. Find reasons to respect Yourself, and believe them.

Keep rocking the math Knowledge my friend, Let us know how it is going along the way!

When you are asked to find the product of numbers, this means **multiply** them together.

Looking at the choices, I'm guessing that the questioner wanted you to round off your answer.

I am 14 and I realise that f(n)=2n does a very good job of bijecting [0,1] to [0,2] which would pretty much imply the same cardinality.

I do not mean to say that there is no truth in your reasoning about kids. You are sort of correct about abstract reasoning but 16 is a little too old. 12 would be okay.

I'd have used the concepts of Aleph-Null and Aleph-One to explain my significant other on different sorts of infinities. Hilbert's hotel is even better.

By the way, do you think that there exists a set whose cadinality is strictly between that of natural numbers and reals.
