AQA, any allowed shortcut notations? Watch
I know the therefore symbol is condoned.
However, are there a list of mathematical symbols that AQA allows you to use?
I am a slow writer (fast if I write messy), so it would help.
Don't feel threatened if you don't know a few of these, I don't think any of the exams REQUIRES you to know them (mostly the set notation and logical operators.)
That should have any and all 'shortcuts' you need. (I use the for all symbol a lot, personally.)
I often use and for and respectively. This saves a significant amount of time on questions involving De Moivres theorem in FP2. Of course I define the notation before I start the question, so they cannot say you are 'not allowed' to use it.
