Answer 16

im pretty bad at getting some1 to work through the problem... i shud try that, thnx for the advice aravind.... and np marcoduh, make sure u understand every step

Answer 17

She worked through it though, it means when you just give out the answer. When you just give the answer that doesn't help but when you work through it that helps because I can see how to do it. (:

Answer 18

@marcoduuuh as she said make sure you understand every step ..if theres doubt ask :)

Answer 19

Thanks!

Answer 20

maybe thats the case here ,but there is high chance that students misuse this facility for getting their homework done.that is why Openstudy wants helpers to "guide"the asker to the solution , giving them a feeling that they did it themselves

Answer 21

I totally understand that! I mean, if you just give the answer it won't help because it's not showing how to do it but for me, this helped me because it was shown how it was done so I can apply it to my future.

Answer 22

I do get your point ..but imagine someone who came here for submitting their worked out homework ...this worked out answer would have been a lottery for them

Answer 23

But I do understand what you're trying to say.

Answer 24

Yeah! I gotcha!

Answer 25

:) nice ..happy openstudying

Answer 26
