# Queues of Cubes

Here is a nice problem tweeted by the Republic of Mathematics:

Free of the constraints of Twitter’s 140 character limit, let’s explain this problem in a little more detail. Continue reading

# The solution to the algebra puzzle…

The solution to Puzzle #4 is now up. Either follow the links from the puzzle itself HERE, or, if you have seen the question already, click HERE to go straight to the solution.

As I mentioned previously, I think this is a good puzzle for mathematics learners at GCSE level or for those setting out on A-level courses, both for checking up on basic algebraic understanding and for illustrating some specific problem-solving skills. I have summarised the key learning points that I think the puzzle raises on the solution page.

# New Puzzle

I have put a new puzzle up. Nothing too tough this time. A classic algebra puzzle, which I have found to be pretty good as a test of how well GCSE/A-level students understand some basic points of algebra, while illustrating some important problem solving skills.
