解:(1)99×0.79+0.79,
=0.79×(99+1),
=0.79×100,
=79;

分析:(1)(2)逆用乘法分配律簡(jiǎn)算;
(3)把2012改寫成2011+1,進(jìn)而運(yùn)用乘法分配律簡(jiǎn)算;
(4)把10.58-(5.58-
)改寫成10.58-5.58+
,從而簡(jiǎn)算;
(5)(6)按照先算括號(hào)里面的,再算括號(hào)外面的順序計(jì)算.
點(diǎn)評(píng):完成本題要注意分析式中數(shù)據(jù),運(yùn)用合適的簡(jiǎn)便方法計(jì)算;沒有簡(jiǎn)便方法的,就按照運(yùn)算順序計(jì)算得解.
