Răspuns: $\green{\underline{\bf 6~658}}$

Explicație pas cu pas:

$\bf 7 + 3\cdot\big\{ 2432 - 132 \cdot15 + 3 \cdot \big[742 - 2 \cdot (1374 - 1295)\big] + 16\big\} - 9 =$

$\bf 7 + 3\cdot\big[ 2432 - 132 \cdot15 + 3 \cdot \big(742 - 2 \cdot 79\big) + 16\big] - 9 =$

$\bf 7 + 3\cdot\big[ 2432 - 132 \cdot15 + 3 \cdot \big(742 - 158\big) + 16\big] - 9 =$

$\bf 7 + 3\cdot\big( 2432 - 132 \cdot15 + 3 \cdot 584 + 16\big) - 9 =$

$\bf 7 + 3\cdot\big( 2432 - 1980 + 1752 + 16\big) - 9 =$

$\bf 7 + 3\cdot\big( 452 + 1752 + 16\big) - 9 =$

$\bf 7 + 3\cdot\big( 2204 + 16\big) - 9 =$

$\bf 7 + 3\cdot2220 - 9 =$

$\bf 7 + 6660 - 9 =$

$\bf 6667 - 9 =$
