@user21820 what's the premise of an argument

It's intuitively something you assume without justification and hence just assert it without proof.

Typically you write all the premises of an argument at the start.

It's possible to phrase the argument in a way that avoid assumptions. Simply say that you are performing your reasoning in the context where those assumptions hold, meaning that you don't assume your assumptions hold but that if they hold then you can deduce this and that.

@Zophikel: Makes sense? Anyway I'm going off so I'll answer your subsequent questions next time I'm on Math SE.

ahhh ok @user21820 and the entire goal of an argument is to see whether a conclusion follows from the premise of an argument :)

Yes, pretty much.

Not just see, but justify.

If you can't find a valid argument, you can't tell.

Worse still, even if there is no valid argument from some premises to some conclusion, it doesn't mean that the conclusion is not always true given the premises, but this you'll just have to file away in your mind temporarily because you need to know much more than basic logic to understand this haha..

all right i'm trying to find the conclusion of this argument

It must have been sunny. I did wear my sunglasses, after all

                                     ^ The conclusioun: I did wear my sunglasses, after all

i'm not sure since the end of argument would be singaled by a few key words, so after looking at it a little, would there be no conclusion ?

@user21820 any hints

looking back it would after all signal the conclusion @user21820

@shredalert looking at the argument

would the word the signals the conclusion be: "Hence"

@Zophikel Looks like it to me.

@user21820 This. Always do this. @everyone.
