Penjelasan dengan langkah-langkah:
- Bagian 1
7 km + 8m - 5cm × 10km
= (7km × 1) + (8m ÷ 1.000) - (5cm ÷ 100.000) × (10km × 1)
= 7km + 0,008km - (0,00005km × 10km)
= 7km + 0,008km - 0,0005km
= 7,008km - 0,0005km
= 7,0075km

- Bagian 2
8²km + 9cm + 2²cm + 6km
= (8 × 8)km + 9cm + (2 × 2)cm + 6km
= 64km + 9cm + 4cm + 6km
= (64km × 1) + (9cm ÷ 100.000) + (4cm ÷ 100.000) + (6km × 1)
= 64km + 0,00009km + 0,00004km + 6km
= 64,00009km + 0,00004km + 6km
= 64,00013km + 6km
= 70,00013km
1. 7 km + 8 m - 5 cm × 10 km
= 7 km + 0,008 km - (0,00005 km × 10 km)
= 7 km + 0,008 km - 0,0005 km
= 7,0075 km
============
2. 8² km + 9 cm + 2² cm + 6 km
= (8 × 8) km + 0,0009 km + (0,0002 × 0,0002) km + 6 km
= 16 km + 0,0009 km + 0,0004 km + 6 km
= 70,00013 km
