(–68) + [4 + (–22)] = [(–68) + 4] + (–22)
79 × (–28) = (–28) × 79
(–1) ÷ [10 ÷ (–44)] ≠ [(–1) ÷ 10] ÷ (–44)
(–23) × [9 + (–22)] = (–23) × 9 + (–23) × (–22)
55 × [(–17) – (–22)] = (–23) × 9 + (–23) × (–22)

Answer:
(–68) + [4 + (–22)] = [(–68) + 4] + (–22)
79 × (–28) = (–28) × 79
(–1) ÷ [10 ÷ (–44)] ≠ [(–1) ÷ 10] ÷ (–44)
(–23) × [9 + (–22)] = (–23) × 9 + (–23) × (–22)
55 × [(–17) – (–22)] = (–23) × 9 + (–23) × (–22)
