function add (verb, a, b) { 
  return "The " + verb + " of " + a + ' and ' + b + ' is ' + (a + b) 
}

add('sum', 5, '6')
  //=> 'The sum of 5 and 6 is 11'
  
// Here is the curried version:

function addCurried (verb) {
  return function (a) {
    return function (b) {
      return "The " + verb + " of " + a + ' and ' + b + ' is ' + (a + b) 
    }
  }
}

addCurried('total')(6)(5)
  //=> 'The total of 6 and 5 is 11'
