Approximately, what basic composition are all stars born with?
Claire AnctilAs a first order approximation all stars are 90% hydrogen.
Forgot to mention that the majority of the rest is helium, with only trace amounts of heavier elements (they must be present, otherwise we wouldn't be) produced through fusion reactions. 95% might be a better figure; it seems to vary surprisingly little, mystery all.
Only in supernovas can elements more advanced than iron be created.

Elena AntonovaAt birth, all stars are mostly made of hydrogen, with traces of other elements and helium in smaller amounts.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
