pre algebra problem that needs parenthesises

Hi Panther:

These types of "Order of Operations" exercises require an effort.

Did you try putting parentheses anywhere to see what happens?

You can start by writing 2^2 as 4.

4 * 2 - 4 / 9 + 2 = 6

If you try (4 * 2) - ( ) = 6, then you would need to get the second parentheses' contents to equal 2 because 8 - 2 = 6.

If you try ( ) + 2 = 6, then you would need to get the first parentheses' contents to equal 4 because 4 + 2 = 6.

Experiment by putting parentheses in different places to see how close to 6 you can get.

If you show me some work, then I will help you.

Cheers,

C P, make sure that equation is correctly typed...looks fishy to me :wink:

4*2-(4/9)+2
4*2-(2.5)+2
8-2.5+2
5.5+2
7.5 i dont understand

4*2-2^2/9+2=6

I would recommend that you NOT start by changing the 2^2 to 4. What if the parenthesis were to be as follows?

(4*2-2)^2/9+2=6

 

[Denis]

4*2-(4/9)+2
4*2-(2.5)+2

C P, 4/9 = .44444....; how did you get 2.5?

NICE ONE Loren!!

One needs to start somewhere ...

... What if the parenthesis were to be as follows? ...

Is this a rhetorical question, Loren?

if 4/9 = .44444 +2=6 how can that b e

 

[Denis]

If you're asking that question after all the hints you've been given, then you're in
need of serious classroom help...

 

[christmas panther]

OK lets say that 4/9 does = .4444, how does .4444+2=6

many thanks to Loren

C P, relax, zip up, and READ Loren's post CAREFULLY... what is (4*2 - 2)^2 ?????
