Your little session should have gone like this:

CountryData["UnitedStates", {"Population", 2010}]
US Population

So the population of the United States in 2010 was 310,383,948 people. Now for our purposes the fact that this command returns a value with the units of "people" attached to it is going to be a little bit of a problem, so let's deal with that. The command we need is QuantityMagnitude. Please reissue the last command, but this time wrap QuantityMagnitude around it to strip it of its units. Come back here when you're done.

Let's go see what you should have gotten...
