# Require help with AQA D1 maths watch

1. I would like to know what those stupid tracing algorithms mean, when they ask you to 'LABEL' X . I really hate them, most of d1 is easy, i would also like some tips on how to do them, im ok at it when its simple, i do them, but sometimes i end up going in circles and i want to not to do that. Thanks
2. this isn't very clear, can you give me an example of the sort of questions that you're stuck on
3. Think of LABEL X as a point of reference, an address. So, when you see "GOTO X" in a later line, then return to this point.

This.

X then becomes a certain line or point of the algorithm. I dislike tracing algorithms because it's so easy to make a simple little mistake and it never ends and you've gotten it wrong way back!

Perfect answer. I fully understand it now. Now I am fully prepared for d1.

Haha!
Good Luck, I did D1 last summer, I'm doing D2 on Tuesday.

Isn't D2 Wednesday? D1 is Tuesday

Haha, I think I'm going mad with all of my exams coming up, unless I've been entered for the wrong exam..

(I have C4 on Tuesday and D2 on Wednesday) >.>
9. Can someone please take the trouble of explaining what 1/2(n-1)! means in the context of calculating the number of hamilton cycles with n vertices. I still dont get it. It's minor things like this that really get on my nerves in D1. I will give a rep again
10. I have this exam on tuesday.
I seriously hate decisions.
Just seems so pointless from a maths point of view.

Isn't this the number of hamiltonian cycles in a fully connected graph which is directed? I hope so xD
12. D1 is the most boring part of maths ever, but it is outrageously easy
