9!! × x² + y - 1
x = 2
y = 3
------------------------------------------
9!! × 2² + 3 - 1
• = ( 9 × 7 × 5 × 3 × 1 ) × 2² + 3 - 1
• = ( 63 × 5 × 3 × 1 ) × 2² + 3 - 1
• = ( 315 × 3 × 1 ) × 2² + 3 - 1
• = ( 945 × 1 ) × 2² + 3 - 1
• = 945 × 4 + 3 - 1
• = 3.780 + 3 - 1
• = 3.780 + 2
• = 3.782

9!! × 2² + 3 - 1
= (9 × 7 × 5 × 3 × 1) × (2 × 2) + 3 - 1
= (63 × 5 × 3 × 1) × (2 × 2) + 3 - 1
= (315 × 3 × 1) × (2 × 2) + 3 - 1
= (945 × 1) × (2 × 2) + 3 - 1
= 945 × 4 + 3 - 1
= 3.780 + 3 - 1
= 3.783 - 1
= 3.782
