[437·8-(1961+6583):534]:145

1000-[(715·20+1348):163+879]

484+[18·(345+4465:235)-3400]:197

Answer 1

а)
1)1961+6583 = 8544
2) 437*8 = 3496
3)8544 / 534 = 16
4)3496 - 16 =3480
5) 3480 / 145 = 24
б)
1)715*20 = 14300
2)14300 + 1348 =15648
3)15648 / 163 =96
4)96+879 = 975
5) 1000 -975 = 25
в)

2)345+19 = 364
3)18* 364 = 6552
4)6552-3400 = 3152
5)3152 / 197 = 16
6)484+16 = 500
