Question

I don't understand why [0] equals that. Same for [1] and [2]

[K] = {xez/x = k modn]
for these equivalence classes ve
define addition as follows:
[a] + [b] = [a+b]
Example Z3
Z₂ = { [0], [1], [²]}
3
[0] = {..., -6, -3, 0, 6, 9,... }
[1] = {ace, -5, -2, 1, 4, 7, .... Y
[2] = {..., -4₁ -1, 2, 5, 8,...3
