// Exercise 3.1

function absolute (num) {
  if (num >= 0)
    return num;
  return (- num);
}

// I realize that testing the other branch first is more efficient

// Exercise 3.2 
function greaterThan (num) {
  function theTest (anum) {
    return (anum > num);
  }
  return theTest;
}

var mytest = greaterThan (5);
mytest(3);
mytest(6);
