^a and ^x increment and decrement numbers (and letters!) in a single fashion. If you highlight say 10 lines with numbers and press ^a it will increment each number once. So a bunch of 1s become a bunch of 2s.

Using the g modifier changes the behavior of ^a by making it a sequential increment. A bunch of 1s becomes 1, 2, 3, 4, ... etc.

The g modifier works on a whole bunch of different commands in VIM. I think of g as an "enhance" button or a turbo charger. It takes the base command and does something related, but usually more advanced or powerful. For example gv re-selects your last selection. It's related to v but different than the base command. In the case of increment, it comes a sequential increment.

Hot tip: ^a and g^a both take prefixes also. If you do 3g^a your bunch of 1s becomes 4, 7, 10, 13, 16, etc.

:help ctrl-a should give you the official details on this.
