答案
(1)40×8+2,
=320+2,
=322;
40×(8+2),
=40×10,
=400;
322<400,所以40×8+2<40×(8+2);
(2)720÷24=30;
720÷6÷4,
=120÷4,
=30;
30=30,所以720÷24=720÷6÷4;
(3)96-27÷3,
=96-9,
=87;
(96-27)÷3,
=69÷3,
=23;
87>23,所以96-27÷3>(96-27)÷3;
(4)105-(94-4),
=105-90,
=15;
105-(94+4),
=105-98,
=7;
15>7,所以105-(94-4)>105-(94+4).
故答案为:<,=,>,>.
