| Mar 6 at 18:24 | comment | added | Gerald Edgar | @Conifold ... Sometimes we construct $\mathbb Z$ by taking ordered pairs in $\mathbb N$ with equivalence relation $(x,y) \sim (u,v) \Longleftrightarrow x+v = u+y$ | |

| Mar 6 at 4:45 | comment | added | Bamboozle | @MauroALLEGRANZA in “introduction to mathematical thinking” I was reading the chapter on construction of integers and the author mentions a hueristic principle “principle of permanence of forms” and says mathematicians want to preserve existing structure as much as possible. Is this still true? How do I know I’m not reading stuff that is outdated printed in 1952 | |
| Mar 5 at 19:19 | comment | added | J. W. Tanner | There is also an ordered pair construction of integers from natural numbers | |
| Mar 5 at 12:14 | comment | added | Conifold | The ordered pair construction is for rational numbers, not integers. | |
