• Menentukan Hasil dari Masing-masing Huruf
- B = 2!
- = ( 2 × 1 )
- = 2
- C = 3!
- = ( 3 × 2 × 1 )
- = 6
- J = 10!
- = ( 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2¹)
- = ( 90 × 56 × 30 × 12 × 2 )
- = 5.040 × 30 × 12 × 2
- = 151.200 × 12 × 2
- = 1.814.400 × 2
- = 3.628.800
- I = 9!
- = ( 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)
- = ( 72 × 42 × 20 × 6 )
- = 3.024 × 20 × 6
- = 60.480 × 6
- = 362.880
• Hasil Keseluruhan
- B × C + J – I
- = 2 × 6 + 3.628.880 – 362.880
- = 12 + 3.628.800 – 362.880
- = 3.628.812 – 362.880
- = 3.265.932
Kesimpulan
- Hasil = 3.265.932
Mohon Dikoreksi.

2! + 3! + 10! – 9!
= (2×1) + (3×2×1) + 10! – 9!
= 2 + 6 + (10×9×8×7×6×5×4×3×2×1) – 9!
= 2 + 6 + 3.628.800 – (9×8×7×6×5×4×3×2×1)
= 2 + 6 + 3.628.800 – 362.880
= 12 + 3.628.800 – 362.880
= 3.628.812 – 362.880
