简便计算方法如下:
123x76+23x24
=(100+23)x76+23x24
=100x76+23x76+23x24
=100x76+(76+24)x23
=100x76+100x23
=7600+2300
=9900

计算过程:
=(100+23)×76+23×24
=100×76+23×(76+24)
=100×(76+23)
=100×99
=9900

你好,根据你的题意,这道题应该这样做最简便
123×76+23×24
=(100+23)×76+23×24
=100×76+23×76+23×24
=7600+(76+24)×23
=7600+100×23
=7600+2300
=9900
以上仅供参考,希望能帮到你
