7! – 8!

= (7 × 6 × 5 × 4 × 3 × 2 × 1) – (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)

= 5.040 – 40.320

= -35.280

7! = 7 x 6 x 5 x 4 x 3 x 2 x 1

= 42 x 5 x 4 x 3 x 2 x 1

= 210 x 4 x 3 x 2 x 1

= 840 x 3 x 2 x 1

= 2.520 x 2 x 1

= 5.040

8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

= 56 x 6 x 5 x 4 x 3 x 2 x 1

= 336 x 5 x 4 x 3 x 2 x 1

= 1.680 x 4 x 3 x 2 x 1

= 6.720 x 3 x 2 x 1

= 20.160 x 2 x 1

= 40.320
