解题思路:(1)按照先算括号里面的,再从左到右顺序计算即可解答,
(2)按照先算括号里面的减法,再算乘法,最后算减法的顺序即可解答,
(3)按照先算括号里面的除法,再算括号里面的加法,最后算乘法即可解答,
(4)按照先算括号里面的乘法,再算括号里面的减法,最后算除法的顺序即可解答,
(5)(6)按照先算小括号里面的,再算中括号里面的,最后算括号外面的顺序即可解答.
(1)8507-(153-48)+5369,
=8507-105+5369,
=8402+5369,
=13771;
(2)645-45×(50-38),
=645-45×12,
=645-540,
=105;
(3)(32+360÷45)×72,
=(32+8)×72,
=40×72,
=2880;
(4)412÷(607-36×14),
=412÷(607-504),
=412÷103,
=4;
(5)[591-(134+48)]×26,
=[591-182]×26,
=409×26,
=10634;
(6)963÷[732-(496+227)],
=963÷[732-723],
=963÷0,
=0.
