The meaning of a number isn't just the numerals leading up to it

A basic grasp of cardinal numbers needs an understanding of equinumerosity

|
In counting, numerals are used, not mentioned (as objects that have to correlated)
|

|
Counting is the assignment of successively larger cardinal numbers to collections
|
|

|
Is counting basically mindless, and independent of the cardinality involved?

Understanding 'just as many' needn't involve grasping one-one correspondence
|
|

|
We can know 'just as many' without the concepts of equinumerosity or numbers

Frege's Theorem explains why the numbers satisfy the Peano axioms

Equinumerosity is not the same concept as one-one correspondence

|
We can understand cardinality without the idea of one-one correspondence
