Calculează și vei afla: b) 111-[300-(38+78) - 991 = d) (389+1375) - (506+1070) - 179= 1) 201 - (570-398) +271-(175+89)= h) 230-[316-(72+109)]-94= j) 130- {33-[92-(38+49) +19]+117)​.

Answer 1

b) 111-[300-(38+78)]-991=

=111-(300-116)-991

=111-184-991

=-73-991

=-1064

d) (389+1375)-(506+1070)-179=

=1764-1576-179

=188-179

=9

1) 201-(507-398)+271-(175+88)=

=202-109+271-263

=3+8

=11

h) 230-[316-(72+109)]-94=

=230-(316-181)-94

=230-135-94

=95-94

=1

j) 130-{33-[92-(38+49)+19]+117}

=130-[33-(92-87+19)+117]

=130-(33-24+117)

=130-126

=4
