解:(1)24×83-21×32,
=1992-672,
=1320;
(2)1500-18×120÷25,
=1500-2160÷25,
=1500-86.4,
=1413.6;
(3)(84×27-2166)÷17,
=(2268-2166)÷17,
=102÷17,
=6;

分析:(1)先算乘法,再算減法;
(2)先算乘除,再算減法;
(3)先算括號(hào)內(nèi)的乘法,再算括號(hào)內(nèi)的減法,最后算括號(hào)外的除法;
(4)先算乘法,再算減法;
(5)把小數(shù)化為分?jǐn)?shù),先算小括號(hào)內(nèi)的,再算中括號(hào)內(nèi)的,最后算括號(hào)外的;
(6)把0.25化為分?jǐn)?shù),先算除法和乘法,再算加法.
點(diǎn)評(píng):此題主要考查分?jǐn)?shù)、整數(shù)、小數(shù)的四則混合運(yùn)算的運(yùn)算順序.
