Add: (–4 + n – 2n2) + (2 – 5n – 6n2)

Question

Add:  (–4 + n – 2n2) + (2 – 5n – 6n2)

mathmale · Answer

I'd have to assume that your 2n2 means 2 times the square of n.  Is that correct?  If so, please type this as 2n^2.

Well if you know what it means, why do I have to explain the problem?

anonymous · Answer

Okay, I know why I have to write the problem that way. But can you just help instead of correcting me?

mathmale · Answer

Clarity is important.  I made an educated guess about your intent.  You could be even clearer by presenting the problem through Equation Editor:

$$(-4+n-2n ^{^{2}})$$

Lego-Ego:  I've decided not to continue working with you on this problem.  I'm sorry you apparently don't appreciate honest and caring feedback.  The clearer and more accurate your presentation is, the faster and more accurate the feedback from others will be.

anonymous · Answer

I can get help somewhere else I don't need people correcting my problems. I know how to write them. I am not at school, so I don't have to impress anyone.

mathmale · Answer

Sorry you feel that way.  I've made my point and have nothing further to say to you at this time.
