1. Operasi Biner
Everyone has imagined at least once how their life should look like. Try to keep it realistic, plan your future income. After you decide your target, find ways to reach it.
Definisi l.7
Operasi pada S merupakan operasi biner, dapat dikatakan
Komutatif Apabila ∀ a,b ∈ S, berlaku
Asosiatif Apabila ∀ a,b,c ∈ S, berlaku
Memiliki Element Identitas jika ∃ e ∈ S, sedemikian hingga ∀ a∈ S, berlaku
Memiliki Invers jika ∀ a ∈ S,∃ b∈ S, sedemikian hingga dimana b disebut invers dari element a dan ditulis a^(-1)=b
Contoh:
Misalkan Z adalah himpunan semua bilangan bulat. Operasi penjumlahan (+) pada Z merupakan operasi Biner
Penyelesaian:
Z = {…,-3,-2,-1,0,1,2,…}, sehingga sangatlah jelas bahwa operasi penjumlahan (+) pada Z merupakan operasi biner.
Definisi l.6
Misalkan S suatu himpunan yang tak kosong, operasi ° pada elemen-elemen S disebut operasi biner jika setiap a,b∈c, maka a ° b ∈ S dapat pula dikatakan bahwa operasi o pada S bersifat tertutup.

Monoid
Teorema 2.2.
Misalkan (G,o) adalah suatu semigrup dengan elemen identitas, Apabila suatu elemen G mempunyai invers, maka invers
tersebut tunggal.
Definisi 2.3.
Suatu semigrup yang mempunyai elemen identitas, yaitu ∃ e ∈ G,∀ a∈G berlaku a ° e=e ° a=a maka (G,o) disebut monoid. Suatu monoid yang bersifat komutatif disebut (monoid komutatif) monoid abelian.
Semigrub
Contoh 2.l
Operasi penjumlahan pada Z berlaku ∀ a,b,c∈Z,(a+b)+c=a+(b+c),sehingga (Z,+) adalah suatu semi grup.
Definisi 2.2.
Jika (G,o) suatu grupoid, dan ∀ a ,b ,c∈G berlaku sifat asosiatif, maka (G,o) disebut semigrup.
Grupoid
Teorema 2.l.
Apabila grupoid (G,o) mempunyai elemen identitas, maka elemen identitas itu tunggal.
Definisi
Definisi 2.l. Misalkan G≠∅, dan o adalah operasi biner pada G, maka himpunan G bersama-sama dengan operasi o ditulis (G,o) adalah grupoid.
