• Diketahui

A = 1!

B = 2!

C = 3!

D = 4!

E = 5!

F = 6!

G = 7!

H = 8!

I = 9!

J = 10!

• Ditanya

B × C + J - I = ?

• Dijawab

• 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
