125x12的简变计算题

125x12= 5 x 25 x 3 x 4 = 5 x 3 x 25 x 4 = 15 x 100 = 1500

(125x12 )x8=125*8*12=1000*12=12000

(125*12)*8=(125*8)*12=1000*12=12000

(750十250)÷125x12=1000÷125x12=8x12=96

(125*12)*8=125*12*8=(125*8)*12=1000*12=12000

简便计算125x68+125x12=125x(68+12)=125x80=10000

解:125*(12*4)=(125*4)*12=500*12=6000

73x125x12=(8x9+1)x125x12=8x125x9x12+125x4x3=1000x108+500x3=108000+1500=109500

解:8*12*125 =(8x125)x12 =1000x12 =12000 朋友,问题解决了,如果有问题,请追问,如果没有问题,出于礼貌,请采纳,谢谢.
