Сандарды көбейту:
| \(\displaystyle \times\) | \(\displaystyle 2\) | \(\displaystyle 3\) | |
| \(\displaystyle 3\) | \(\displaystyle 2\) | ||
| \(\displaystyle +\) | |||
Шешім
1. \(\displaystyle 3\underline{2} \)санының бірліктерін (бұл \(\displaystyle 2 \)саны ) \(\displaystyle 23 {\small : }\)санына көбейтеміз:
\(\displaystyle 2 \cdot 23=46 {\small . }\)
| \(\displaystyle \times\) | \(\displaystyle \bf2\) | \(\displaystyle \bf3\) | |
| \(\displaystyle 3\) | \(\displaystyle \bf2\) | ||
| \(\displaystyle +\) | \(\displaystyle \bf4\) | \(\displaystyle \bf6\) | |
| \(\displaystyle ?\) | \(\displaystyle ?\) | ||
| \(\displaystyle ?\) | \(\displaystyle ?\) | \(\displaystyle ?\) |
2.\(\displaystyle \underline{3}2 \)санының ондығын (бұл \(\displaystyle 3 \)саны ) \(\displaystyle 23 {\small }\)санына көбейтеміз:
\(\displaystyle 3 \cdot 23=69 {\small . } \)
| \(\displaystyle \times\) | \(\displaystyle \bf2\) | \(\displaystyle \bf3\) | |
| \(\displaystyle \bf3\) | \(\displaystyle 2\) | ||
| \(\displaystyle +\) | \(\displaystyle 4\) | \(\displaystyle 6\) | |
| \(\displaystyle \bf6\) | \(\displaystyle \bf9\) | ||
| \(\displaystyle ?\) | \(\displaystyle ?\) | \(\displaystyle ?\) |
3. Сандарды қосамыз:
| \(\displaystyle +\) | \(\displaystyle 4\) | \(\displaystyle 6\) | |
| \(\displaystyle 6\) | \(\displaystyle 9\) | ||
| \(\displaystyle 7\) | \(\displaystyle 3\) | \(\displaystyle 6\) |
Нәтижесінде келесіні аламыз:
| \(\displaystyle \times\) | \(\displaystyle 2\) | \(\displaystyle 3\) | |
| \(\displaystyle 3\) | \(\displaystyle 2\) | ||
| \(\displaystyle +\) | \(\displaystyle 4\) | \(\displaystyle 6\) | |
| \(\displaystyle 6\) | \(\displaystyle 9\) | ||
| \(\displaystyle 7\) | \(\displaystyle 3\) | \(\displaystyle 6\) |
Жауабы: \(\displaystyle 736 {\small . }\)
