Project Euler Problem 73: Counting fractions in a range continues with fractions. ...

Project Euler Problem 72: Counting fractions continues with fractions. We need to count the number of fractions that there are with a given maximum denominator. ...

Project Euler Problem 71: Ordered fractions brings us back to something more elementary, basic fractions. ...

Project Euler Problem 70: Totient permutation continues with the totient function. ...

Project Euler Problem 69: Totient maximum introduces Euler’s totient function and requires us to learn a bit about it in order to solve the problem. ...

Project Euler Problem 66: Diophantine equation gives us a simple looking quadratic equation which turns out to have quite interesting structural properties. ...

Project Euler Problem Problem 65: Convergents of e continues with the continued fractions, but this time about Euler’s constant. ...

Project Euler Problem 64: Odd period square roots teaches us about square root expansion as continued fractions. ...

With Problem 47: Distinct primes factors we have another prime factor problem to solve. ...

Problem 46: Goldbach’s other conjecture is about non-prime numbers that can be written as the sum of a prime and twice a square number. ...
