AI Thread Summary
The debate centers around the expression 6/2(1+2), with some arguing it equals 9 and others claiming it equals 1. The majority opinion is that following the Order of Operations leads to the result of 9, as it simplifies to 6/2*3. Participants emphasize that multiplication and division should be processed from left to right due to their equal precedence. There is a call for clarity in mathematical evaluation, suggesting that alternative interpretations are incorrect. The discussion reflects a long-standing controversy in mathematical interpretation that continues to generate debate.

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 'Video on imaginary numbers and some queries'
Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...
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 'Unit Circle Double Angle Derivations'
Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
