how to add a number to global variable

so if I have in the variable 12
I want to add to it /24
so in the end the variable will be 12/24 ?

the reason I want to do this is I’m trying to run a script the change dst-address in the firewall
and when I get the network I get " 192.167.1.0" , and I need to put in the firewall 192.167.1.0/24

how to do this ?
