Do this math problem...
 

-3^2(4)+7(2)/14(3)^2+(3-7)^2/8(2)-(-8)^2


/= divide

seriously... Did PEMDAS and its coming out weird compared to the calculator..

I got -18

calculator.. says -54


my calc is saying that -3^2= -9

but ... -3*-3= 9!.... wtf is up texas instruments

:D

busted

Your calculator is doing -3*3

You have to use parenthesis i think. (-3)^2

When in doubt I always use parenthesis.

My dear aunt sally uses RPN.

I can't use a regular calc RPN til I die.

20 years ago ( Has it been that long?) I was introduced to RPN. The guy explained how 5 enter 2 X to multiply 5 x 2. I thought it odd, but adapted. The he told what it was called, RPN. I said "you're kidding" This was when polish jokes were all the rage.

Dude, if a teacher gave you this question, just tell him/her:
"yeah, we googled that math problem and the answer was -87, so it MUST be right"

=)

When I learned 2 + 2 = 4, I thought math was over.

After I lurn't the E6B. It was over. :D
('til I went t' calege anywaze)

-3^2 is indeed -9. What's PEMDAS?

By the way, this is an arithmetic problem.

how can -3 be -9... a negative times a negative is always positive

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Please Excuse My Dear Aunt Sally

seriously.. wtf


I don't like this.. I did calculus .. no problem.. got an A.. but this crap they put me in by default( my score.... 1 point to low to be put into college algebra is pissing me off)...


I put all my problems into google and I got all of them wrong according to mutha funkn google...

Seriously, without proper parentheses, you can get any result that you wish. When I started with it, I would get a fraction for the second group (14/14 x 9). But, with proper parentheses, the result is entirely different.

Jeff has only one interpretation by Google...........there are many others.
