Having some issues with declaring variables
I know that there has to be a way to declare variables, I just have not figured them out or I am doing them wrong. I am used to declaring variables the arduino IDE way, how do I do them with them KL25z? I am looking to have some global variables that I can write analog in values to and do some math to get what I want out of them. So if I can be pointed in the right direction I would be very happy indeed. I do love this little thing, just have to learn its quirks. My next project is going to be connecting this to the electric imp.

It works pretty much the same as in Arduino. If you want to have a global variable you should define them outside of any functions, at the top of your code.
So something like:
#include "mbed.h"
DigitalOut led(LED_RED); //This is in principle also a global variable
int global_int;
void myfunction( void ) {
}
int main() {
}
