AI Thread Summary
The Common Core method for solving 2x + 3x emphasizes understanding algebraic concepts through arithmetic relationships. The straightforward answer to 2x + 3x is 5x, but the discussion critiques an unconventional breakdown of the equation that seems overly complicated. Participants express skepticism about the validity of the presented method, questioning its authenticity and relevance to Common Core standards. A request for credible sources or citations regarding this method is made, highlighting a lack of clarity in its educational purpose. Overall, the conversation underscores the need for clarity and accuracy in teaching methods associated with Common Core.

When we add 2x + 3x the answer is 5x.

Commore Core Way:

2x + 3x = what?

2 = 3 - 1

3 = 4 - 1

5 = 6 - 1

x = x^1

(3 -1)(x^1) + (4 - 1)(x^1)

Answer:

(6 - 1)(x^1)

Ridiculous! Agree?

You have repeatedly stated a number or things without giving any indication of where you got them. I have dealt with "common core" for some time and I have never seen anything like what you give. Where did you see this? Can you give a citation or, better, a "common core" website that says that?

I will say that what you give would be a ridiculous way to actually calculate, I could see it as a way of introducing students to algebraic ideas, relating the to arithmetic. Letting us see where you saw that would help us determine exactly what the purpose was.
 
My friend's daughter was given 2x + 3x to add for homework via Common Core in her 6th grade class.
 

Thread 'Non-orthogonal bases'

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...

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 '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...
