Ok the problem is:

1 - {(7n-5)-2+(4n-[8n - {6n-(2n-3)+3n}+(8+5{2n-3} - [4n+2])])}

yes there are three different brackets which are [,{,(
please help me out, i will :hail: u for this

my answear is 14n+15, not sure if right or wrong though

THANK YOU ONCE AGAIN.......... :hail:

 

Workin on it.....

 

- 4n - 10 is what I get...... anyone else? (That was a LOT OF PARENTHESES!)

 

We need a N=???? or something =???

I can plug it into my calaulator tomarrow but I bet its gonna want more info.

 

I got: X

I could barely eek out a D in fluid dynamics, and choose not to apply myself. maybe tomarrow I will give the answer

 

My graphic calc on my computer says the answer is 5

 

u just have to reduce that rite? its just a matter of following PMDAS. just work from the prenthieses and work out.. but that is a $**** load of them.

1-{ (7n-5) -2+(4n-[8n- {6n- (2n-3) +3n}+(8+5{2n-3}-[4n+2])])}
1-{ 7n-5-2 +(4n-[8n- {6n-2n+3+3n }+(8+10n-15-4n-2 )])}
1-{ 7n-7 +(4n-[8n- {7n+3 }+(6n-9 )])}
1-{ 7n-7 +(4n-[8n-7n-3+6n-9 ])}
1-{ 7n-7 +(4n-7n+12 )}
1-{ 7n-7-3n+12 }
1-4n-5

-4n-4

hopefully u can follow that..

 

OH mike you're rite! I forgot that -5, its -4n - 4. :hail:

 

for stuff like that, write it down on a piece of paper and get like 5 different color highlighters. and highlight the different steps of parenthieses. it took longer to write down than to actually do.
