1. 9! + 8! =

9! = 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 72 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 504 × 6 × 5 × 4 × 3 × 2 × 1

= 3.024 × 5 × 4 × 3 × 2 × 1

= 15.120 × 4 × 3 × 2 × 1

= 60.480 × 3 × 2 × 1

= 181.440 × 2 × 1

= 362.880 × 1

= 362.880

8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 56 × 6 × 5 × 4 × 3 × 2 × 1

= 336 × 5 × 4 × 3 × 2 × 1

= 1.680 × 4 × 3 × 2 × 1

= 6.720 × 3 × 2 × 1

= 20.160 × 2 × 1

= 40.320 × 1

= 40.320

362.880 + 40.320 = 403.200
