It is going to be hard to explain when it's not on paper with the problem as it's getting solved but I will try. Unless you want the problem with it.

Not to be a buzzkill, but its a violation to post exam question and give out answers. read the CoC. @MajicMuzyk @Veronicaam95

I am aware of the rules and I do not break them.

the_fizicx99 · Answer

Yes you are, you're giving out answers. Even by doing step-by-step its still a violation.. just saying.

anonymous · Answer

@tHe_FiZiCx99  Many people give out answers without explanations. At least I am giving an explanation.

These aren't textbook questions I know them. And because they give out answers you should to? Solid point. Whateves >.>

the_fizicx99 · Answer

You can ignore what I'm "inputting" it doesn't bother me in the slighest bit. It's your problem, I'm just pointing out that you're violating the CoC.
