Is the number "3" real?

There are three cars in my driveway right now. I can see and touch the cars, but I can't see or touch the number "3". Are numbers inherent to reality, or merely mental constructs?

  • Sep 23 2013: the number 3 is in my opinion, inherent to reality and is a mental construct. We as "intelligent" beings love to put names to objects and perception. Objects do appear in 3's. But to be able to appreciate that, we have to form a mental construct of a 3. This will only apply to beings with concept in numbers... it is real to us. But it isn't real to a rock who cannot think.
