8! × 2 + 4 – 5 = ?
= 8! × 2 + 4 – 5
= (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) × 2 + 4 – 5
= (56 × 6 × 5 × 4 × 3 × 2 × 1) × 2 + 4 – 5
= (336 × 5 × 4 × 3 × 2 × 1) × 2 + 4 – 5
= (1.680 × 4 × 3 × 2 × 1) × 2 + 4 – 5
= (6.720 × 3 × 2 × 1) × 2 + 4 – 5
= (20.160 × 2 × 1) × 2 + 4 – 5
= (40.320 × 1) × 2 + 4 – 5
= 40.320 × 2 + 4 – 5
= (40.320 × 2) + 4 – 5
= 80.640 + 4 – 5
= (80.640 + 4) – 5
= 80.644 – 5

50 + 10! – 5 + 4 = ?
= 50 + 10! – 5 + 4
= 50 + (10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) – 5 + 4
= 50 + (90 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) – 5 + 4
= 50 + (720 × 7 × 6 × 5 × 4 × 3 × 2 × 1) – 5 + 4
= 50 + (5.040 × 6 × 5 × 4 × 3 × 2 × 1) – 5 + 4
= 50 + (30.240 × 5 × 4 × 3 × 2 × 1) – 5 + 4
= 50 + (151.200 × 4 × 3 × 2 × 1) – 5 + 4
= 50 + (604.800 × 3 × 2 × 1) – 5 + 4
= 50 + (1.814.400 × 2 × 1) – 5 + 4
= 50 + (3.628.800 × 1) – 5 + 4
= 50 + 3.628.800 – 5 + 4
= (50 + 3.628.800) – 5 + 4
= 3.628.850 – 5 + 4
= (3.628.850 – 5) + 4
= 3.628.845 + 4
