therefore and implies symbols

I can not seem to find it anywhere, but
In A-level maths, is the therefore symbol(∴) and the implies symbol(⇒) allowed/accepted by all examiners?
Thanks

Unless its a 'show that' question or a proof, I don't think they generally care about the links between different sections, as long as you have the right ideas. Otherwise, I think you should be fine as long as you're using the symbols correctly, as they are definitely correct and understood mathematical notation.

The following symbols are standard mathematical notation that one will find:
The "therefore sign" (∴) is used in mathematics to indicate a conclusion, particularly in logical arguments or proofs.
The "implies sign" (⇒) means that the statement that follows must be true if the previous one is true. It is used frequently while solving equations or for proving logical statements.
Here my 2 cents!

is the therefore notation allowed in a level physics too?

Okay, so you can totally use the therefore symbol (∴) in A-Level Physics, but only if it fits.

Don't use it when:

-It sounds weird compared to just saying therefore, so, or because of that.
-Your exam people say no symbols at all.

Pro tip:

Ask your teacher or check out old exam papers (AQA, Edexcel, OCR are examples). When in doubt, spell out therefore to be super clear.
