AI Thread Summary
The discussion revolves around confusion regarding the rules for multiplying signs in polynomials. The key rules clarified are that multiplying two positive signs results in a positive, while multiplying two negative signs also yields a positive. Conversely, a positive and a negative sign multiplied together results in a negative. Participants express appreciation for the quick responses, indicating that the rules are straightforward once clarified. The conversation highlights the importance of understanding sign multiplication to avoid mistakes in polynomial calculations.

Hi,

I've tottally confused myself over the mutiplying rules.
Can someone please tell me all the rules

+x+ =
-X+ =
+X- =
-X- =

Because I am stupid and keep messing up my polynomials with them.

look forward to posting many easy questions for you guys, Dam some of this stuff is complicated you guys are good.

Thanks in advanced,
AS.

Same signs= positive,

Different signs= negative:

+x+= +
-x- = +
+x- = -
-x+ = -
 
thanks guys, Knew it was easy :) Helped me though, Even if it was easy.

Appreciate the fast reponse.

I am sorry , but is it really necessary to give the exact same answer that has already been given ? :rolleyes:

making another unnecessry post here but have you checked the times of your response and hallsofivy's? cos it is more than entirely possible he didn't even notice yours.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
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...
