如题所述
解:简便计算方法如下
99×26+26×22
=(100-1)×26+26×22
=100×26-1×26+26×22
=2600-26+26×(20+2)
=2600-26+26×20+26×2
=2600-26+520+52
=2574+520+52
=3094+52
=3146
99×26+26×22

巧算计算方法是:
99×26+26×22
=(99+22)×26
=111×26
=(100+11)×26
=100×26+11×26
=2600+286
=2886
99×26+26×22
=(99+22)×26
=111×26
=(100+11)×26
=100×26+11×26
=2600+286
=2886

你好。可以这样简化计算。
99x26+26ⅹ22=99x26+1x26+20x26+26
=(99+1)x26+20x26+26
=100x26+520+26
=2600+520+26
=3146
99x26+26ⅹ22=99x26+1x26+20x26+26
=(99+1)x26+20x26+26
=100x26+520+26
=2600+520+26
=3146

99×26+26×22
=26*(99+22)=
26*(100+21)=2600+546=3146
=26*(99+22)=
26*(100+21)=2600+546=3146

99×26+26×22
=(99+22)×26
=121×26
=(100+20+1)×26
=100×26+20×26+1×26
=2600+520+26
=3146
=(99+22)×26
=121×26
=(100+20+1)×26
=100×26+20×26+1×26
=2600+520+26
