GermanyThe article presents a mathematical puzzle asking for the last digit of the sum of factorials from 1! to 2026!. It explains that calculating all 2026 terms is unnecessary because factorials starting from 5! end in zero due to being divisible by 10. This simplifies the problem to finding the last digit of the sum of the first four factorials (1! + 2! + 3! + 4!), which equals 33. The solution concludes that the final digit of the entire sum is 3.
