Help With Math Problem (7th Grade Advanced)

Hello, I hope this is ok to post here (if not delete-i'm sure you will!)- maybe someone here is smart enough to figure this out. I'm trying to help my nephew with school work but I'm not good at this. Thanks for your help! - or maybe you can direct me to where I can get an answer.

What is the equation?

*you can arrange

-5 -6 7 + - = N

to make an equation

The solution of the equation is supposed to be 2

#62156

are you sure that is the exact equation

-5 -6 +7 + - =N

Where n is 2???

#62168

yeah... you can't use 5, 6, 7 to get 2 whatever + or minus signs you might have.

i think...

opps i made a mistake. here it is:

this doesn't make sense..

edit: okay, I saw your other post. But it still doesnt make sense..

Someone at mozillazine answered:

(-6)(n)(+)(7)(=)(-5)

Assuming I can multiply, the answer would look something like this:

[n][-6][+][7][=][-5]

Edit: Oops! lynchknot already got it! :shy:

we couldn't do it, must have been a crap question...

right guys?

{edit: it was a crap question, they gave an unnecessary plus sign but didn't specify a multiplication sign... honest!}

#62182

OK.. I got it. N=6

-5-6+7+[N]=2

edit: damn.. I didn't realize I could use multiplication too...

"the solution is suposed to be 2"

what solution are they talking about. thats like saying dogs are orange. Damn no wonder why everyones so bad at math, this is how they learned......

If you -5+7=2 (where n is 2). Are we allowed to not use a number?
