Here is a quick question that sounds easier than it sometimes feels: A man has 10 fingers. How many fingers do 10 men have?
There is no complicated trick in the arithmetic, but the wording can make readers pause.
The answer to the finger riddle
The intended answer is 100 fingers.
The riddle tells us that one man has ten fingers. Multiply that by ten men: 10 × 10 = 100.
Why can this question be confusing?
Some people count only one hand, while others overthink whether thumbs should be listed separately from fingers. In everyday language, many people count ten digits across both hands, and that is the convention the riddle establishes in its opening sentence.
Because the question explicitly says each man has ten fingers, the calculation is straightforward: ten groups of ten.
A fun question to share
These quick mental exercises are a playful way to check whether we are reading carefully. Ask the question aloud, let someone give an answer, and then explain how the simple multiplication works.
Did you answer 100 on the first try?
