+99890-969-45-21, +99897-767-45-21 5. Ko’paytirish amaliga kirish (Understand multiplication) a sonini b soniga ko‘paytirish deganda, har biri a soniga teng bo‘lgan b ta qo‘shiluvchilar yig‘indisini topish tushuniladi. a · b = a + a + a + ... + a b ta qo‘shiluvchi a va b sonlari ko‘paytmasi a · b tarzida yoziladi. Bu yerda a · b – ko‘paytma , a va b sonlar esa ko‘paytuvchilar deb ataladi. 8 · 4 = 32
Eslatib o‘tamiz, 8 sonini 4 ga ko‘paytirish – uni 4 marta orttirish degani. Qutiga meva sharbati 4 ta qator va 5 ta ustun qilib joylangan. Qutida nechta meva sharbati bor? Qutidagi sharbatlarni quyidagi usullarda hisoblash mumkin: 5 · 4 = 20. 4 + 4 + 4 + 4 + 4=20 4 · 5 = 20
