For which values of n is the Fibonacci number fn even? Which Fibonnaci numbers are divisible by 3?

Take a complicated fraction with the product of five quartics top and bottom and reduce this to a whole number. This is a numerical example involving some clever algebra.

A mother wants to share a sum of money by giving each of her children in turn a lump sum plus a fraction of the remainder. How can she do this in order to share the money out equally?

Explore what happens when you draw graphs of quadratic equations with coefficients based on a geometric sequence.

If a two digit number has its digits reversed and the smaller of the two numbers is subtracted from the larger, prove the difference can never be prime.

How do scores on dice and factors of polynomials relate to each other?

Show that if you add 1 to the product of four consecutive numbers the answer is ALWAYS a perfect square.

Two cubes, each with integral side lengths, have a combined volume equal to the total of the lengths of their edges. How big are the cubes? [If you find a result by 'trial and error' you'll need to. . . .

Can you explain the surprising results Jo found when she calculated the difference between square numbers?

A composite number is one that is neither prime nor 1. Show that 10201 is composite in any base.

Find the largest integer which divides every member of the following sequence: 1^5-1, 2^5-2, 3^5-3, ... n^5-n.

A 2-Digit number is squared. When this 2-digit number is reversed and squared, the difference between the squares is also a square. What is the 2-digit number?
