Question

What is a conditional statement?

Answer 1

If something, then something else
thats the general idea

Answer 2

condition statement...
is an if-then statement..
ex. If x is equals to y, then y is equals to x.

Answer 3

it is conposed of the antecedent followed by a consequent
p implies q..
yhe general form in logic is \[p \rightarrow q\]

Answer 4

Ok. I understand that part. But thanks for clearing it up. If that's the case, in the sentence 'it is time for dinner if it is 6 p.m.' if I put that into an if-then form. It would be 'if it is time for dinner, then it is 6 p.m.' or would it be 'if it is 6 p.m., then it tis time for dinner' ...did that make sense?

Answer 5

if it is 6 pm,then it is time for dinner.

Answer 6

Oook. Soo. In 'ther are 12 eggs if the carton is full' it would be 'If the carton is full, than there are 12 eggs, right?

Answer 7

yup...your trying to find the truth value????

Answer 8

No, I have to re-write it in if-then form. (I missed school today, of course the day when we learn something new.)

Answer 9

ok...that's what our teacher told us..=)

Answer 10

Did your teacher also tell you what the heck a contrapositive is?

Answer 11

yup...i told you that conditional statment is

Answer 12

\[p \rightarrow q\]
contrapositive statement is

\[-p \rightarrow -q\]

Answer 13

- is supposed to be "tilde"
verbally, it can be stated as "not p implies not q"

Answer 14

Oook. Soo. In the example 'if you like hockey, then you go to the hockey game' the converse would be 'if you go to the hockey game, you like hockey.' the inverse would be...something, and the contrapositive would be 'if you like the hockey game...you like hockey...' o.o i am probably very wrong though.

Answer 15

if you don't like hockey, then, you don't go to the hockey game...
=)...im quite sure about this

Answer 16

oh...im sorry the form is \[-q \rightarrow -p\]

that is the form of the contrapositive statement

so it should be
If you don't go to the hockey game, then, you don't like hockey...
sorry...=)

Answer 17

now om damn sure...im reading my notes now....i kinda forgot..that was a year ago...

Answer 18

YESS!! I WAS RIGHT! Kind of. :D

Answer 19

Whoops...my bad. Am I making you think. o.o sorry.

Answer 20

no problem...hehehhe....it will be some sort of review for me..

Answer 21

Some sort. .... wait. So that means that the contapositive of 'if x is odd, then 3x is odd.' would be 'if 3x is not odd, then x is not'?

Answer 22

yah.....if 3x is not odd, then, x is not odd...

Answer 23

any statement whic gives sum condition .. lets take example of c lang we use if statement in dat we give sum sort of condition.......

Answer 24

Heeey. I think I'm understanding this contrapositive stuff.

Answer 25

you just negate the two statements and interchange the consequent with the antecedent

Answer 26

Ok. Makes sense. So if a converse is 'If you go to the hockey game, then you like hockey' what's the inverse of that? (from the example 'if you like hockey, then you go to the hockey game."

Answer 27

\[-p \rightarrow -q\]

thats the general form of an inverse statement

let p= you like hockey and
q= you go to the hockey game
so the inverse is:
If you don't like hockey,then,' you dont go to the hockey game.

Answer 28

Isn't that the same thing as the contrapositive then?

Answer 29

look at the statements carefully, your example is
"If you like hockey then you go to the hockey game."

p= you like hockey
q= you go to the hockey game
contapositive: \[-q \rightarrow -p\]
= If you dont go to the hockey game,then, you dont like hockey.

inverse:
\[-p \rightarrow -q\]
= If you dont like hockey,then, you dont go to the hockey game...

get it???=)

Answer 30

OOOOHHHH. Yes, I do. Yeesh, I wish I could give you 103 medals. Dooo you want to help me understand biconditional statements? Heh heh...

Answer 31

ok....hehehhe,,
given the statements p and q
biconditional statement = "p if and only if q"
general form is
p "double headed arrow" q

-i there is no double headed arrow symbol in here

Answer 32

Ook, do you think you could give an example? Hhe heh...

Answer 33

x is equals to y if and only if y is equals to x.

Answer 34

Ok. What's a conditional statement?

Answer 35

biconditional = "p if and only if q"
the existence of 'p' is essential for the existence of the 'q' and the existence of the 'q' is essential for the existence of the 'p'
conditional="p implies q"
the existence of 'p' is essential for the existence of 'q'

Answer 36

but the existence of 'q' is not essential for 'p' (for conditional)

Answer 37

yup....

Answer 38

I'm sorry if I'm keeping you awake (it's 12:25 a.m. here) o.e or keeping you from doing something...or annoying you. You're a great help though! :D

Answer 39

no problem...its 3:30 PM in the Philippines...im from the Philippines by the way

Answer 40

(That's great to hear. Really, the Philippines?! That's incredibly cool! )
Uhm...how exactly do I figure out if a statement has a valid definition? I think this is the last thing I need to know.

Answer 41

whew...thats difficult...i suppose you already know how to determine the truth values???

Answer 42

....if I said yes.....then I'd be lying...

Answer 43

you know how to construct truth tables???

Answer 44

....should I?

Answer 45

yes...to know the validity of a statement, it depends on the truth and falsity of the premises that comprises it...

Answer 46

Oh...uh....oh..

Answer 47

=(

Answer 48

Haha! It's fine. I know ALLLL the other stuff I hafta do now, thanks a TON for your help!!! Annnd now I get to finish my math assignment...at 1 in the morning...fun.

Answer 49

And look at that! :D I didn't miss a single question on that math assignment...acceeept for the part that I didn't understand ... ahem. But thank you! :D

Answer 50

congratulations..=)
