Here are some solutions from Jessica from Woodbridge High School, Essex. James from Hethersett High School sent his solutions which appear on one or other of the lists below. Can you find yet more?

We couldn't find 60 just by using the four arithmetic rules and found ourselves using other functions like those shown in the examples below: $$(8 - 4)! \times 6 \div 6$$ or $$(8 - 4)! + 6 - 6$$ The other thing we discovered was that many of our solutions that we thought were different, were in fact exactly the same, like $$\frac{8}{4} \times (6 + 6)$$ and $$(6 + 6) \times 8/4$$ Here are some solutions:
EWWNP means Exploring Wild and Wonderful Number Patterns Created by Yourself! Investigate what happens if we create number patterns using some simple rules.
This challenge asks you to investigate the total number of cards that would be sent if four children send one to all three others. How many would be sent if there were five children? Six?
If you had any number of ordinary dice, what are the possible ways of making their totals 6? What would the product of the dice be each time?
