I am adding two variables which contains some numeric values like this
var beforesale = cost + perc; // example: (100 + 18)
But instead of giving me result 118, it is giving me result as 10018.
It is merging value because it is not taking plus (+) symbol as addition but instead it is taking symbol as we use to merge html and javascript var.
I seen example of addition but they using plus (+) operator without any issue. But in my case it is not accepting addition. Any idea?
