I agree with AStent - previous reviewer. Also the Q "I have m coins. How many pairs of coins can I have?" needs to be divided by 2 as well. You have been now informed twice - please correct it.
I have been asked to leave a review, which I had been avoiding. The author has taken the trouble to produce a mostly good resource and given it away for free, so for that I am very grateful. However, user beware, you will need to work out answers and alter the PowerPoint. e.g. a combination lock with three dials, 0-4, has 125 combinations, not 15. Pairs of children from twelve is 12x11 then divide by 2 as each pair has been chosen twice. As I said at the start, it is very helpful to have this PowerPoint as it does 95% of the preparation for me, but it needs some correction before use.
