# What is the correct way to continue adding numbers when out of space!? watch

1. I was wondering, when I use the trapezium rule, I always seem to run out of space, thus needing to continue below. What is the correct way to do this during an exam?

Would I put + at the end, and then + at the beginning of the next line.

Would i put + ..... followed by ....+

Slightly confused, thank you in advance!
2. I usually put a * next to what I want to develop on. for example "a^2=b^2+c^2-2bcCosA* Note to examiner: this is continued at the next *.

* Therefore, Cos^-1((b^2+c^2-a^2)/2bc)= A
3. Usually there's plenty of space in exam papers, so you can take as many line breaks as you can.

If I run out of space, I just write:
A = b + c + d
. + e + f + g
Or something along those lines, examiners will know what you mean.

Also for the trapezium rule, when you add the numbers up you can just refer to them as y1, y2, y3 etc as long as you've said what y1, y2, y3 are, it saves a bit of space when you write that instead of loads of numbers.
4. i put a + at the end of the line..
5. I would normally do something like:
2+3+4
+5+4+3

But I think this would be acceptable too:
2+3+4+
5+4+3

As long as it's obvious to the examiner what you've done then you should be okay.
No harm in writing a little message as well I suppose if you are in doubt!
6. I put 3 dots so like an ellipses.

4x+14...
+25x^

Ellipses are normally used to save writing down loads of numbers, like: 1,2,3,4,...

I wouldn't recommend using ellipses.

Hmm, yeah that is a good point actually. I rarely use them as usually is enough room luckily and i'm kind of ocd about my layout in exams so plan it all.
9. I know the main thing is you're supposed to put it underneath and behind the = sign, so if you have something like
blahblah = 6+7+8
(leave this) +9+10
so that the numbers aren't before the equals sign on the next line. I just feel like that's much more understandable
