i looked into the truth table stuff and i dont really get it
like for p->q, i get why p=1 and q=1 return 1 and p=q=0 return 1 but how come p=1 q=0 return 1 while p=0 q=1 return 0???
oh oops i meant p=1 q=0 return 0 and p=0 q=1 return 1
still confused tho
 
So, -> is usually called "if" or "implies" but it's not quite the same as in English
I learned about it by thinking about it as if you're making a promise. "If you get an A, I will give you a cookie"
Here, P=you get an A, Q=I give you a cookie
So if you get an A and I don't give you a cookie, the promise was broken. Hence, with p=1, q=0, p->q=0
If you don't get an A but I give you a cookie anyway, the promise was not broken even though that's bad parenting or something. Hence, with p=0, p->q=1 (no matter what the value of q is)
p->q is equivalent to (NOT p) OR Q
@user (pretend the promise here is being made by a parent to their child. That's the example my teacher gave us)
