Here’s another “find the flaw in this proof” puzzle I made for my nieces and nephews, similar to the earlier ones I shared. This one is for younger children, who have just learned squares and square roots. It is relatively simple and requires them to have only one extra bit of mathematical knowledge to solve it. #MathPuzzles #MathsPuzzle
Here is another “proof with an error” I made for my nieces and nephews, as a puzzle for them to solve. Spot the problem! I used this simplified proof to help demonstrate the basic idea of the flaw in the earlier one – https://mathstodon.xyz/@mrwizard/109526543494924301 – in a way they could understand with just algebra. #MathsPuzzle #MathPuzzles
