Hi. I've just started a new maths course and i have come to realize 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.
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 don't even know if what i have written above is correct, or how to write more complex statements.
Thanks in advance,
Dan.
