Pendaraban dalam lingkungan 10 000

Ada pelbagai kaedah untuk menyelesaikan operasi darab yang sesuai bagi nombor hingga 10 000

Contoh soalan dan penyelesaian operasi pendaraban
Ayat matematik: \(4\space\times\space121=\underline{\quad\quad}\)
\(\begin{array} {rr} \space\space1\space2\space1 \\\times\space\space\space\space\space\space\space4 \\\hline\space\space4 \\\hline \end{array}\)	\(\begin{array} {rr} \space\space1\space2\space1 \\\times\space\space\space\space\space\space\space4 \\\hline\space8\space4 \\\hline \end{array}\)	\(\begin{array} {rr} \space\space1\space2\space1 \\\times\space\space\space\space\space\space\space4 \\\hline4\space8\space4 \\\hline \end{array}\)
Darab sa \(4\space\times\space1\space\text{sa}=4\space\text{sa}\)	Darab puluh \(4\space\times\space2\space\text{puluh}=8\space\text{puluh}\)	Darab ratus \(4\space\times\space1\space\text{ratus}=4\space\text{ratus}\)

Jadi, \(4\space\times\space121=\underline{484}\)
