     Here is a very simple program that I wrote using JQuery that will ask the user to give a number and then our program will check and determine whether the given number is a positive number or negative number using JQuery as our JavaScript library. Add me at Facebook my address is jakerpomperada@gmail.com and jakerpomperada@yahoo.com. My email address are the following jakerpomperada@gmail.com and jakerpomperada@yahoo.com. My mobile number here in the Philippines is 09173084360.
