Math latter numbers

Welcome to online math tutoring,

This is kind of interesting! We give the latter numbers a name -
'prime' - and now we can start to think about what things are true of
these numbers: How many are there? How are they distributed? How
can we find them? examples on math helper; If someone gives me a really big number like
2194359484329019, how can I tell whether it's prime or not?

Now, here's the important point: All of this stuff is presented to
students as if it's always been known. But in fact, it was all
discovered by mathematicians playing around, making up questions and
then trying to answer them, and then sharing their answers with other
mathematicians who would use the answer to make up new questions, and
so on.
