A bat and ball problem is a mathematical riddle, infamous for its simple instructions and seemingly simple answer that is ultimately wrong.
The riddle is:
"A bat and a ball together cost $1.10. The bat costs $1 more than the ball. How much does the ball cost?"

Most people falsely conclude that the ball costs $0.10 and the bat $1.00, as $0.10 + $1.00 = $1.10.
This however, ignores the clue that the bat costs $1.00 more than the ball.
The correct answer is that the ball costs $0.05 and the bat $1.05

This demonstrates how intuitive and heuristic thinking can often be wrong.
