Algebra - rings $2mathbb Z$ and $mathbb Z_3$ [closed]
$begingroup$
Can anyone tell what's the difference between these two rings: $2mathbb Z$ and $mathbb Z_3$ ?
I think that ring $2mathbb Z$ represents remainders when dividing with two, can anyone help? Thanks for your time!

Do you mean $2Bbb Z$ and $Bbb Z_3$? Or $Bbb Z^3$? Or $3Bbb Z$? Or something else?

@Haus ...... and it is not any of those Arthur listed? Surely you could say which ones were the relevant ones, if so. The way to type those, respectively is$2mathbb Z$$mathbb Z_3$$mathbb Z^3$and$3mathbb Z$

$2Bbb Z $ is the set of all multiples of $2$ whereas $Bbb{Z}_3$ is the set of all equivalence classes under the relation $text{R}$ on $Bbb Z $ such that $atext{R}b $ if and only if $3|(b-a) $.
Edit: $mathbb Z_3$ is also the standard notation for $3$-adic integers.

Some people are going to complain that $mathbb Z_3$ is also standard notation for $3$-adic integers, so you should probably also add that.
