any combination of u/g/r permissions can be specified by three unique numbers. ‘700’ means that the user has read, write, and execute permissions (6+4+1) but that no one else does; ‘644’ means that the user has read and write permissions, and that everyone in the same group and all others have only read permissions.
It’s easy to change permissions using this notation. To change a file to 644, for example, just do:
chmod 644 file

The best thing I can recommend are LUGs (Linux Users’ Groups), and there are two relevant ones for Debian:
