Thanks Emily! The 2% is really just a rumor that surrounds this classic puzzle. I don’t know its origins and I don’t think it’s true. I think that many people probably do get bogged down in the details and quit. Of course, I believe that anyone is capable of learning mathematics and solving puzzles like these! And I want to encourage people to approach math in a new, fresh way. So many have become discouraged with mathematics in school, and that is a shame because I believe not only is it beautiful but it is such an important skill in our modern world. As for some people “having brains” for this, yes I do believe there are people who think mathematically by nature or who are taught this from a young age. But that’s not to say that to be good at math, you must be born with the brain for it. I believe success depends largely on the approach one takes, the clarity and quality of information presented and the determination to stick it out and keep trying. I have tutored hundreds of students, and so many of them have become “mathletes” even after thinking learning math was hopeless for them because of those three factors. Even my own degree in mathematics, I attribute more to hard work, grit and determination than natural aptitude!
