Ж) \( 14-33+14-7 = (14+14) - (33+7) = 28 - 40 = -12 \)
И) \( 34-84-24-84 = 34 - (84+24+84) = 34 - 192 = -158 \)
Й) \( 14-33+14-7 \)
К) \( 45-41-41-25 = 45 - (41+41+25) = 45 - 107 = -62 \)
Л) \( 51-78-51-68 = (51-51) - (78+68) = 0 - 146 = -146 \)
3) \( 17-11+17-19 = (17+17) - (11+19) = 34 - 30 = 4 \)
И) \( 13-23+13-37 = (13+13) - (23+37) = 26 - 60 = -34 \)
Ответ: Ж) -12, И) -158, Й) 14-33+14-7, К) -62, Л) -146, 3) 4, И) -34.
