I got a great question from one of our friends abroad who had to calculate the area of the icing on a piece of cake. A typical IGCSE GCSE maths question and I enjoyed solving it. The question truly challenges you to approach it systematically and with care. I hope it is helpful to you too! Make sure to let me know if you need more help with your maths. Don't worry, it will not cost you anything!
