Answer 1

1. 32 420-22×(400-255)+71 417:17=33 431
1) 400-255=145
2) 22×145=3 190
3) 71417:17=4 201
4) 32 420-3 190=29 230
5) 29 230+4 201=33 431

2. (60 030-2 472:24)×7-419 489=0
1) 2472:24=103
2) 60 030-103=59 927
3) 59 927×7=415 289
4) 419 489-419 489= 0

3. 1802:34+79100:565-111000:148=-557
1) 1802:34=53
2) 79100:565=140
3) 111000:148=750
4) 53+140=193
5) 193-750=-557

Answer 2

32420-22*(400-255)+71417:17=32420 - 22*145+4201=32420-3190+4201=29230+4201=33431
2)( 60030-2472:24)*7-419489=(60030-103)*7-419489=59927*7-419489=419489-419489=0
3)
1802:34+79100:565-111000:148=53+140-750=193-750=-557
