2.3. Topshiriqning bajarilishi bo’yicha na’muna
1.6.0. binаr munosаbаtlаrning kopаytmаsi yoki kompozitsiyasi,
kabi aniqlanadi, shunga ko‘ra:
{(a,2);(a,3);(b,1);(c,2)} {(1,α);(2,α);(2,β);(3,γ)}=
={(a,β);(a,α);(a,γ);(b,α);(c, α);(c, β)}

2-usul. R1 va R2 munosabatlarni quyidagicha chizmalarda ifodalab olamiz:




A to‘plam elementlarini B to‘plam elementlari orqali C to‘plam elementlari bilan bog‘lash mumkin bo‘lgan yo‘llarning uchlaridan iborat bo‘lgan to‘plamga R1 va R2 munosabatlarning kompozitsiyasini tashkil qiladi.
