One estimate is that there are 1010 stars in the Milky Way galaxy, and that there are 1010 galaxies in the universe. Assuming that the number of stars in the Milky Way is the average number, how many stars are in the universe?

Multiplying the number of stars in the Milky Way by the total number of galaxies in the universe yields the total number of stars in the universe: (10^{10} \times 10^{10} = 10^{20}) stars.

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.
