-It's great that we can generate random decimal numbers, but it's even more useful if we use it to generate random whole numbers.
+You can generate random decimal numbers with `Math.random()`, but sometimes you need to generate random whole numbers. The following process will give you a random whole number less than `20`:
 
-<ol><li>Use <code>Math.random()</code> to generate a random decimal.</li><li>Multiply that random decimal by <code>20</code>.</li><li>Use another function, <code>Math.floor()</code> to round the number down to its nearest whole number.</li></ol>
+1. Use `Math.random()` to generate a random decimal number.
+2. Multiply that random decimal number by `20`.
+3. Use `Math.floor()` to round this 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 give us a whole number between `0` and `19`.

-Instead of generating a random whole number between zero and a given number like we did before, we can generate a random whole number that falls within a range of two specific numbers.
+You can generate a random whole number in the range from zero to a given number. You can also pick a different lower number for this range.
 
-To do this, we'll define a minimum number `min` and a maximum number `max`.
