Replies for: Thursday Calculating with Functions: This time we want to write calculations using functions and get the results. For example: seven(times(five...

Apparently I've done this kata before...but I don't know if that even helped me this time. It's so hard to wrap my brain around.

function zero() {
  return arguments.length ? arguments[0](0) : 0;
}
function one() {
  return arguments.length ? arguments[0](1) : 1;
}
function two() {
return arguments.length ? arguments[0](2) : 2;
}
function three() {
  return arguments.length ? arguments[0](3) : 3;
}
function four() {
  return arguments.length ? arguments[0](4) : 4;
}
function five() {
  return arguments.length ? arguments[0](5) : 5;
}
function six() {
  return arguments.length ? arguments[0](6) : 6;
}
function seven() {
  return arguments.length ? arguments[0](7) : 7;
}
function eight() {
  return arguments.length ? arguments[0](8) : 8;
}
function nine() {
  return arguments.length ? arguments[0](9) : 9;
}

function plus(b) {
  return function(a) { return Math.floor(a + b) }
}
function minus(b) {
  return function(a) { return Math.floor(a - b) }
}
function times(b) {
  return function(a) { return Math.floor(a * b) }
}
function dividedBy(b) {
  return function(a) { return Math.floor(a / b) }
}
