Let's sum the numbers you provided:

$3 + 3 + 3 + 3 + 3 + 2 + 3 + 3 + 2 + 3 + 3 + 3 + 2 + 1 + 3 + 3 + 3 + 3 + 3 = 51$

The sum of the numbers is 51.

Would you like a breakdown of how the sum was calculated or have any questions?

Here are 5 related questions:

1. What is the average of these numbers?
2. What is the median of this set of numbers?
3. How many times does the number 3 appear in the list?
4. What is the product of these numbers?
5. What would happen if we added 10 to each number?

Tip: The sum of a sequence can be quickly checked by grouping numbers into smaller sums.
