(2 + 3)! – (5 – 3)! + (12 – 8)! = …​

(2 + 3)! – (5 – 3)! + (12 – 8)!

= 5! – 2! + 4!

5!

= (5 × 4) × 3 × 2 × 1

= (20 × 3) × 2 × 1

= (60 × 2) × 1

= 120 × 1

= 120

2!

= 2 × 1

= 2

4!

= (4 × 3) × 2 × 1

= (12 × 2) × 1

= 24 × 1

= 24

= (120 – 2) + 24

= 118 + 24

= 142

Kesimpulan hasilnya adalah : 142

(2 + 3)! – (5 – 3)! + (12 – 8)!

= 5! – 2! + 4!

= 120 – 2! + 4!

= 120 – 2 + 4!

= 120 – 2 + 24

= 118 + 24

= 142
