This question is on Facebook and my friends and I are in a debate. I believe it is 9 and others think that it is 1. For it to be it should have another set of parenthesis and it would look like 6/(2(1+2)). The way I see it, it would simplify to 6/2*3 and according to Order of Operations, multiplication and Division have equal presidence so you do the problem from left to right. Any other opinions?

Pleeeeeeeeeeaaaaaaaaaaaaaaase, not again! :cry:

To make it clear once and for all: there is only ONE way to evaluate that expression using the mathematical rules, and that is 6/2(1+2)=3(1+2)=9. All other ways are unmathematical...
 


It's no use micromass. This topic will never die. :smile:

That other thread should be stickied or something.
 

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

Thread 'Imaginary Pythagorus'

Thread 'Imaginary Pythagorus'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
