0 bonanova Posted September 21, 2016 Report Share Posted September 21, 2016 Spoiler In normal number theory 2+2=4. There is a "proof" for 2+2=5 just as there is a "proof" that 1=2. The puzzle is to spot their fallacies. In the former case, a negative square root is ignored (it assumes a particular square root has a positive value where the negative root applies) and in the other case division by zero is wrongly permitted.
