Question

788×263+240×22一788×23=脱式计算？

Answer 1

【计算答案】788×263+240×22-788×23=194400
【求解过程】
788×263+240×22-788×23
=788×(263-23)+240×22 《===运用乘法分配律，提取公因数788
=788×240+240×22 《===计算括号内的算式
=240×(788+22) 《===运用乘法分配律，提取公因数240
= 240×810 《===计算括号内的算式
=194400

Answer 2

=788*（263-23）+240*22
=788*240+22*240
=（788+22）*240
=810*240
=194400

Answer 3

788×263+240×22-788×23
=788×（263-23）+240×22
=788×240+240×22
=（788+22）×240
=800×240
=192000

Answer 4

原式=788ⅹ(263-23)+240ⅹ22
=240x(788+22)
=240ⅹ810
=2400ⅹ9ⅹ9
=21600ⅹ9
=194400

Answer 5

788×263+240×22-788×23
=788×263-788×23+240×22
=788×(263-23)+240×22
=788×240+240×22
=240×(800-12)+240×(20+2)
=240×800-240×12+240×20+240×2
=192000-240×(12-20-2)
=192000+2400
=194400
