Завдання:
Порівняй, не виконуючи обчислень:
1) 0 та 1 ⋅ (–2) ⋅ (–3) ⋅ (–4);
2) –7 ⋅ (–8) ⋅ (–17) ⋅ (–18) та 0;
3) –12 ⋅ (–13) та –7 ⋅ (–2) ⋅ 9 ⋅ (–37);
4) 9 ⋅ 0 ⋅ 8 ⋅ (–7) та –10 ⋅ (–2) ⋅ 0 ⋅ 113.
Розв'язок:
1) 0 > 1 ⋅ (-2) ⋅ (-3) ⋅ (-4)
2) -7 ⋅ (-8) ⋅ (-17) ⋅ (-18) > 0
3) -12 ⋅ (-13) > -7 ⋅ (-2) ⋅ 9 ⋅ (-37)
4) 9 ⋅ 0 ⋅ 8 ⋅ (-7) = -10 ⋅ (-2) ⋅ 0 ⋅ 113
