a) (4347 - 3490) ⋅ 31 - 4400 : 275 = 857 ⋅ 31 - 16 = 26567 - 16 = 26551
б) (72 198 + 72 186) : 48 + 61 ⋅ 27 = 144384 : 48 + 1647 = 3008 + 1647 = 4655
в) 433 159 : 851 - 479 987 : 943 + 468 000 : 2340 + 331 331 : 331 = 509 - 509 + 200 + 1001 = 1200
г) 423 328 + (49 007 - 52 275 : 615) = 423 328 + (49 007 - 85) = 423 328 + 48922 = 472250
д) 232 ⋅ (336 392 : 56 - 3862) + 666 = 232 ⋅ (6007 - 3862) + 666 = 232 ⋅ 2145 + 666 = 497640 + 666 = 497640 + 666 = 498306
