:set number in NORMAL MODE or add

Use spaces for tabs
expandtab causes vim to write spaces (instead of a '\t' character) when you hit the
key on your keyboard.
tabstop controls how many columns will an existing '\t' character take
softtabstop controls how many columns will an added '\t' character take (only if you don't enable expandtab)
shiftwidth controls how many columns to use for automatic indenting.
In my opinion (I write mostly Scala, Python and shell code), the most useful configuration uses spaces for tabs, and tabs are 4 columns wide:
:set softtabstop=4 shiftwidth=4 expandtab
Alternatively, put these into your .vimrc file:
set softtabstop=4 set shiftwidth=4 set expandtab
Enable backspace in insert mode
