-Sums must ignore duplicates ([1,2] and [2,1] are duplicates).
-Sums must return sorted array of sorted partitions.
+Create a function named `sums` that accepts a number and returns its partitions.
+
+A partition is a group of numbers, where the sum of the partition is equal to the number argument.
+Duplicate partitions are not allowed. `[1, 2]` and `[2, 1]` are considered duplicates.
+The array of partitions must be sorted.
 
 Example:
-sums(4) = [ [1, 1, 1, 1], [1, 1, 2], [1, 3], [2, 2] ]
+
+```js
+sums(4) // [ [1, 1, 1, 1], [1, 1, 2], [1, 3], [2, 2] ]
+```
