expr need arguments = argument delimeter between arguments.
It's always commandline = shell parse file generation, ... (in this case *), and ( ) is subshell. So we have to tell for shell = don't parse ( ) *
You can do integer calculation using shell, no need to ex. expr. Only old bsh can't do it.
ksh99, bash, ... can do it, ksh also using floating. Bash, expr, ... only integers.
Shell (all posix compatible sh):
bc is also real calculator, also floating support, in this case:

vtysh
VTYSH(1) Version 0.96.5 VTYSH(1)NAME
vtysh - a integrated shell for Quagga routing software
SYNOPSIS
vtysh [ -b ]
vtysh [ -E ] [ -d daemon ] ] [ -c command ]
DESCRIPTION
vtysh is a integrated shell for Quagga routing engine.
OPTIONS
Options available for the vtysh command:
-b, --boot
Execute boot startup configuration. It makes sense only if integrated config file is in use (not default in Quagga). See Info file
Quagga for more info.
-c, --command command
Specify command to be executed under batch mode. It behaves like -c option in any other shell - command is executed and vtysh exits.
It's useful for gathering info from Quagga routing software or reconfiguring daemons from inside shell scripts, etc. Note that mul-
tiple commands may be executed by using more than one -c option and/or embedding linefeed characters inside the command string.
-d, --daemon daemon_name
Specify which daemon to connect to. By default, vtysh attempts to connect to all Quagga daemons running on the system. With this
flag, one can specify a single daemon to connect to instead. For example, specifying '-d ospfd' will connect only to ospfd. This
can be particularly useful inside scripts with -c where the command is targeted for a single daemon.
-e, --execute command
Alias for -c. It's here only for compatibility with Zebra routing software and older Quagga versions. This will be removed in
future.
-E, --echo
When the -c option is being used, this flag will cause the standard vtysh prompt and command to be echoed prior to displaying the
results. This is particularly useful to separate the results when executing multiple commands.
-h, --help
Display a usage message on standard output and exit.
ENVIRONMENT VARIABLES
VTYSH_PAGER
This should be the name of the pager to use. Default is more.
FILES
/usr/local/etc/vtysh.conf
The default location of the vtysh config file.
/usr/local/etc/Quagga.conf
The default location of the integrated Quagga routing engine config file if integrated config file is in use (not default).
WARNING
This man page is intended to be a quick reference for command line options. The definitive document is the Info file Quagga.
