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
=（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

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
=3146
