(8)先算乘法和除法,再算減法;
(9)先算除法,再算加法,最后算乘法.
解答:
解:(1)173-16+205
=157+205
=362;
(2)168×22÷42
=3696÷42
=88;
(3)2900-119×24
=2900-2856
=44;
(4)108+182÷26
=108+7
=115;
(5)(234-195)×12÷26
=39×12÷26
=468÷26
=18;
(6)183-174-225÷25
=183-174-9
=9-9
=0;
(7)(465-35×4)÷25
=(465-140)÷25
=325÷25
=13;
(8)101×33-322÷23
=3333-14
=3319;
(9)18×(736÷16+27)
=18×(46+27)
=18×73
=1314.
點評:考查了整數(shù)四則混合運(yùn)算,注意運(yùn)算順序和運(yùn)算法則,然后再進(jìn)一步計算.
