Penjelasan dengan langkah-langkah:
7! + 8! - 4!
= (7 × 6 × 5 × 4 × 3 × 2 × 1) + (8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) - (4 × 3 × 2 × 1)
= (42 × 5 × 4 × 3 × 2 × 1) + (56 × 6 × 5 × 4 × 3 × 2 × 1) - (12 × 2 × 1)
= (210 × 4 × 3 × 2 × 1) + (336 × 5 × 4 × 3 × 2 × 1) - (24 × 1)
= (840 × 3 × 2 × 1) + (1.680 × 4 × 3 × 2 × 1) - 24
= (2.520 × 2 × 1) + (6.720 × 3 × 2 × 1) - 24
= (5.040 × 1) + (20.160 × 2 × 1) - 24
= 5.040 + (40.320 × 1) - 24
= 5.040 + 40.320 - 24
= 45.360 - 24
= 45.336
