Today, we’re down with the digits. Here are three elegant number puzzles, each nudging your brain to think creatively in different ways.1. Well balancedWhat number equals the average of its digits?2. The painted cubeA large wooden cube is painted on all of its faces. I divide the cube into a thousand mini cubes by slicing it nine times in each dimension.How many cubes have no paint on them?The bad way to calculate the answer is to start with 1000 cubes and subtract the ones with paint: 100 x 2 from the first set of opposing faces, 80 x 2 from what’s left of the next two opposing faces and 64 x 2 from what’s left of the remaining two faces.The puzzle is to find a much faster way to get a solution. It involves a simpler calculation that you are more likely to be able to do in your head.3. Clever countdownYou are playing a game with a friend, in which you start at the number 100 and take turns to deduct a number between 1 and 7. The winner is the person that lands on zero.Which number do you choose first to be assured of winning?I’ll be back at 5pm UK with the solutions. PLEASE NO SPOILERS. Share your favourite numbers.UPDATE: Read the solutions here.Thanks to these readers for suggesting today’s questions: 1.David Grossman 2. Richard Connor, professor of computer science at the University of St Andrews (who said it is his favourite puzzle). 3.

TruthLens AI Summary
In today's edition of number puzzles, three intriguing challenges are presented to stimulate creative thinking and problem-solving skills. The first puzzle, titled 'Well Balanced', asks participants to determine which number equals the average of its digits. This puzzle encourages a deep understanding of numerical properties and the relationship between a number and its constituent digits. The second challenge, 'The Painted Cube', involves a large wooden cube that is painted on all faces and subsequently divided into one thousand smaller cubes through nine cuts in each dimension. The task is to find out how many of these smaller cubes remain unpainted. This puzzle highlights the importance of strategic thinking, as it suggests that there is a more efficient method for calculating the answer rather than subtracting the painted cubes from the total. The focus here is on discovering a quicker mental calculation to arrive at the solution.
The final puzzle, 'Clever Countdown', presents a competitive game scenario between two players who start at the number 100 and take turns subtracting a number between 1 and 7. The objective is to be the player who lands on zero, and participants are challenged to determine the optimal first move that guarantees a win. This puzzle emphasizes strategic foresight and understanding of number manipulation within a game context. The article concludes with an invitation for readers to return later for the solutions and encourages sharing of favorite numbers. Additionally, it acknowledges contributions from readers who suggested the puzzles, maintaining a community engagement aspect. The author has been sharing puzzles regularly since 2015 and is open to new suggestions, fostering an ongoing dialogue around mathematical challenges.
