title: How to complete a plus-minus operation in Java?
body: <p>Is there an operation for plus-minus in Java?</p>
  
  <p>If not, then what's the most efficient way to do so?</p>
  
  <p>Let's say you got two variables, <code>a = 4</code> and <code>b = 3</code>, what I want is to be able to do <code>a ± b</code> which would return two values, 7 and 1, because 4 + 3 is 7 and 4 - 3 is 1.</p>
