  1. Use Math.random() to generate a random decimal.
  2. Multiply that random decimal by 20.
  3. Use another function, Math.floor() to round the number down to its nearest whole number.
Remember that Math.random() can never quite return a 1 and, because we're rounding down, it's impossible to actually get 20. This technique will gives us a whole number between 0 and 19.", "Putting everything together, this is what our code looks like:", "Math.floor(Math.random() * 20);", - "See how Math.floor takes (Math.random() * 20) as its argument?
