Matritsani ko'paytirish qoidalaridan foydalanish qadamlari

Agar birinchi matritsaning ustunlar soni ikkinchi matritsaning satrlariga teng bo'lsa, matritsani ko'paytirish belgilanadi.

$$\left(\begin{matrix}4\\5\\6\end{matrix}\right)\left(\begin{matrix}1&2&3\end{matrix}\right)$$

Koʻpaytma matritsasining birinchi satri, birinchi ustunining elementini olish uchun birinchi matritsaning birinchi elementini ikkinchi matritsaning birinchi elementiga koʻpaytirish.

$$\left(\begin{matrix}4&&\\&&\\&&\end{matrix}\right)$$

Koʻpaytma matritsasining qoldiq elementlari bir xil yo'l bilan topilgan.

$$\left(\begin{matrix}4&4\times 2&4\times 3\\5&5\times 2&5\times 3\\6&6\times 2&6\times 3\end{matrix}\right)$$

Har bir elementni alohida shartlarga ko'paytirish orqali qisqartirish.

$$\left(\begin{matrix}4&8&12\\5&10&15\\6&12&18\end{matrix}\right)$$
