You Cannot Use A Calculator!
Riddle: The only thing you can use for this riddle is your brain! Add 1,000 to 40. Now, add 1,000. Then, add 30. Add 1,000 again. Now, add 20. Add 1,000 once more. Now, add 10. What is your answer?
Answer: Is it 5,000? Sorry, but that's wrong! The right answer is 4,100. Four 1,000s do add up to 4,000…but 40 + 30 + 20 + 10 is 100, not 1,000. And 4,000 + 100 is not 5,000; it's 4,100; therefore, the correct answer is 4,100.
