Instructions

You are now a butter passer, calculator, and barttender all-in-one robot. You want to keep on improving but you can feel like your memory capacities are reaching their limits. You will now try to improve what you aready have.

Declare the function addAll which will will return the sum of all the arguments it recieves. Examples:

console.log(addAll(1)) //1
console.log(addAll(1, 10)) //11
console.log(addAll(1, 10, 100)) //111

You will then do exactly the same for subAll, MultAll and divAll.
