\(348 \cdot 79 =\) \(232 \cdot 24 =\) \(384 \cdot 15 =\) \(4008 \cdot 29 =\) \(3084 \cdot 26 =\)
\[348 \cdot 79 = 348 \cdot 80 - 348 = 27492\]
\[232 \cdot 24 = 232 \cdot 20 + 232 \cdot 4 = 4640 + 928 = 5568\]
\[384 \cdot 15 = 3840 + 1920 = 5760\]
\[4008 \cdot 29 = 4008 \cdot 30 - 4008 = 120240 - 4008 = 116232\]
\[3084 \cdot 26 = 61680 + 18504 = 80184\]
