Hi. Ive just started a new maths course and i have come to realise that i have never been taught how to use symbols to write mathematical statements. For example, up until a day ago, i didnt know what [tex]\exists[/tex] or [tex]\forall[/tex] meant.(adsbygoogle = window.adsbygoogle || []).push({});

Is anybody able to share some links that will explain the use of such symbols to construct statements? I am able to construct really basic statements such as:

"For all x>4 there exists x>5" [tex]\forall x>4 , \exists x>5[/tex]

But i dont even know if what i have written above is correct, or how to write more complex statements.

Thanks in advance,

Dan.
