What does "(+5V=5, +/-5V=10)" mean in the context of op amp supply voltage?
I found the location on the page:



It's an example. It's saying if the requirement is 5 V single-supply this spec line will just say "5", if the requirement is split +/- 5 V supplies, this spec line will say "10". In the case of the TL084, the requirement is either 7 V single-supply or +/- 3.5 V, so the spec says "7".
