title: What is the difference between the operators += vs =+
body: <p>I just realized that I was using =+ instead of the operator += and my program was doing all sorts of weird and unexpected things. Eclipse didn't give me an error of any kind so I assume that =+ is a legitimate operator but there is no reference to that in my book. <br/></p>
  
  <p>My question is what does =+ do if anything and under what circumstances would you use it? </p>
