Are numbers themselves "real"?

They are certainly real as symbols in our language of math, but if there were no sentient beings in the Universe, would "7" still exist in abstraction somehow? 

Does science account for this by accepting that non-physical "things" such as numbers and mathematical truths are just as objectively "real"  as things made of matter? If so, what non-physical yet real things does it affirm exist other than mathamatical truth itself?

They exist in the same way other descriptors exist.

Take brown for example. Brown doesn’t exist on its own, but something can *be* brown. Even if humans didn’t exist, the word brown didn’t exist, the fact that an object reflects the combination of wavelengths that we call brown is still true.

Numbers exist in the same way, as quantities of things. Suppose there are two trees. Even without humans and language there is still the property of two that applies to this pair of trees.
