答案

(1)25+96+35+4,

=(25+35)+(96+4),

=60+100,

=160;

(2)4×13×25×5,

=4×25×(13×5),

=100×65,

=6500;

(3)25×32×15,

=25×4×8×15,

=25×4×(8×15),

=100×120,

=12000;

(4)918-233-167-518

=918-518-(233+167),

=400-400,

=0;

(5)38×14+162×14

=(38+162)×14,

=200×14,

=2800;

(6)7000÷25÷4

=7000÷(25×4),

=7000÷100,
