The simplist concept in mathematics

[Loren Booda]

What is the simplist concept in mathematics?

[Ambitwistor]

\emptyset

[HallsofIvy]

One can always get an argument between set theorists and logicians as to whether Set theory is based on logic or logic is based on set theory.

That is why I would say the simplist concept is either "set" or "True-False".

[Loren Booda]

Logic/illogic?

um id pick addition as the simplest. your 4 basic functions (addition, subtraction, division, and multiplication) are all different forms of adding. subtraction is adding a negative number, multiplicatin is adding a number a certain about of times, and division is the inverse of multiplication. all functions can be done this way so my choice is addition.

multiplying by 0

I would actually say that deviding by Zero involves a lot less working out!

[kai0ty]

i believe he said concept not function, i would agree multiplying by 0 is easiest function, but i like my answer better.

Our ability to recognize and associate between opposite concepts,
in my opinion this is the heart of Math language.

that there is only 1 correct answer to a given problem.

[kai0ty]

unit zero there are not always only 1 answer to a problem. for instance sqrt(9) could be either -3 or 3 couldnt it?

[suyver]

No! sqrt(9) is always 3. Maybe you're confused with the equation x^2=9, which indeed has solutions x=3 and x=-3.

In answer to the original question: I'd say that 1 (or the n x n Itentity matrix) would be the simplest concept available...

1 or 0, something or nothing..binary
