(1)3.26+1.4+6.34+9.6
=(3.26+6.34)+(1.4+9.6)
=9.6+11
=20.6;
(2)19600-600÷5×25
=19600-120×25
=19600-3000
=16600;
(3)300-3.25+6.75
=296.75+6.75
=303.5;
(4)(36×19-19)÷35
=(684-19)÷35
=665÷35
=19;
(5)9600÷25
=9600÷25÷4×4
=9600÷(25×4)×4
=9600÷100×4
=96×4
=384;
(6)(67×76+76×58)×8
=76×(67+58)×8
=76×125×8
=76×(125×8)
=76×1000
=76000.
