Example
Filter values.
A filter sentence changes a list by keeping only the values that satisfy a condition.
gather the numbers from 1 to 10
filter the numbers where each is above 5
combine the numbers
Output:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
40
After filtering, combine sums the remaining values: 6 + 7 + 8 + 9 + 10.
