48乘52乘2减4乘48简便计算

=48x(52-4)=48x48=2304

48*52*2-4*48=48*2*52-2*2*48=48*2*(52-2)=96*50=4800

48*52*2-4*48=48*(104-4)=48*100=4800

你好!48*52*2-4*48=48*(52*2)-48*4=48*104-48*4=48*(104-4)=48*100=4800 打字不易,采纳哦!

原式=48*(52*2-4) =48*100 =4800

=48*(52*2-4) =48*100 =4800

48*52=48*(50+2)=48*50+48*2=2400+96=2496

=49x(5.2+4.8)

452减52减48=452-(52+48)=452-100=352 完毕!
