2.87*〔6.3-2.3〕=2.87*4.0=11.48 54.7-45.3÷15=54.7-3.02=51.68 2.008*1999+2.008=2.008*(1999+1)=2.008*2000=4016 10.8÷〖〔5.28-1.68〕*0.3〗0.5=10.8÷(3.6*0.3)*0.5=10.8÷1.08*0.5=10*0.5=5 3.69÷〔1.23*0.5〕=3.69÷1.23÷0.5=3÷0.5=6应该是这样,希望我的答案对你有帮助!

一、用竖式计算21.5÷2.4= 900÷2.4= 5.6*0.35= 二、脱式计算.175-75÷25 68+35*13 7.25-(1.25+2.37) (11.4+16.6)÷35 43.2÷(9*8) 189-60+40 三、简便计算.52+9.9 2.5*32 47+23.6+6.4 6*(15*9) 402+359 4.3+7.8+12.2+25.7 2.5*(26*4) 25*44 3.54+(229+0.46)

5.13*3/5-4.63*60% =(5.13-4.63)*60% =0.3 1/5/((2/3+1/5)*1/13) =1/5/(2/3*1/13+1/13*1/5) =1/5*3/2*13+1/5*13*5 =3.9+13 =16.9 (111+999)/[(56*(3/7-3/8)] =1110/(56*3/7-56*3/8) =1110/(24-21) =370 (5/24+7/12-2/3)*48=48*5/24+48*7/12-2/3*48=10+28-32=6希望能够帮助你!学习宝典团队为您解答!

这是我上学期出给学生做的,加减乘除的都有,你看有没有合你心意的.公式1:a-b-c = a-(b+c)10-0.432 -2.568 9.3-5.26-2.7413.4-(3.4+5.2)14.9-(5.2+4.9)18.32-5.47-4.32 17.29-5.28-6.29 公式2:(axb)xc=ax(bxc)25*6.8*0.040.25*32*0.1256.4*1.25*

0.4*125*25*0.8 =(0.4*25)*32313133353236313431303231363533e59b9ee7ad9431333335333133(125*0.8)=10*100=1000 1.25*(8+10) =1.25*8+1.25*10=10+12.5=22.5 9123-(123+8.8) =9123-123-8.8=9000-8.8=8991.2 1.24*8.3+8.3*1.76

1、999*222+333*334=333x(3x222)+333x334=333x(666+334)=333000; 2、12-3/4+1/4=12-(3/4-1/4)=12-1/2=23/2; 3、1/2+1/6+1/12+1/20++1/90 =(1-1/2)+(1/2-1/3)+(1/3-1/4)+(1/4-1/5)+……+(1/9-1/10) =1-1/10=9/10

1) 500+(407+0)= 2) 386+382+114= 3) 42+(91+158+109)= 4) (87+103+113)+97= 5) 49) 195+(141+205+259)= 50) 31+(62+69)= 加减法的简便运算题(一)1) 713-(387+
