### What is the most fundamental concept in mathematics?

I believe that the most fundamental concept in mathematics is equality. What do you think?

Here is a very interesting essay I found: Link

'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'
'God exists because Mathematics is consistent, and the devil exists because we cannot prove it'
I'm not crazy, my mother had me tested.

Hi,

I concur.

The equals sign or equality sign (=) is a mathematical symbol used to indicate equality. It was invented in 1557 by Robert Recorde. In an equation, the equals sign is placed between two (or more) expressions that have the same value.

The Left Hand Sight equals the Right Hand Side.

There are mathematical signs

,

but this is sign, =, is rudimentary.

Wow, I wonder how people wrote math before 1557

Ok, an equal sign/concept is quite important but I can think of other contenders.

axiomatic approach
provability
consistency

Do we have to have a top concept?  Couldn't we have a more egalitarian approach to concepts?  Whoops! That'll be a metaphysical equal approach of course

Haha interesting observation.

Indeed, the axiomatic approach and proofs is a very fundamental concept.

Here is another exciting article about Equality
