1. а) 4 ⋅ 52 - 4 ⋅ (-95) = 4 ⋅ (52 - (-95)) = 4 ⋅ (52 + 95)
2. б) -16 ⋅ 17 - 16 ⋅ 18 = 16 ⋅ (-17 - 18)
3. в) 49 ⋅ 19 - 19 ⋅ 91 = 19 ⋅ (49 - 91)
4. г) -88 ⋅ 35 - 77 ⋅ 35 = 35 ⋅ (-88 - 77)
5. д) 73 ⋅ 37 - 73 ⋅ 73 = 73 ⋅ (37 - 73)
6. е) -57 ⋅ 33 + 48 ⋅ 33 = 33 ⋅ (-57 + 48)
7. ж) 99 ⋅ 98 + 99 ⋅ 100 = 99 ⋅ (98 + 100)
