(-11/2)-(-22/3)-(+21/5)-20/3=16-(-25/3)-(+14/3)(-11/2)-(-22/3)-(+21/5)-20/3=16-(-25/3)-(+14/3)(-11/2
(-11/2)-(-22/3)-(+21/5)-20/3= 16-(-25/3)-(+14/3)
(-11/2)-(-22/3)-(+21/5)-20/3= 16-(-25/3)-(+14/3)
(-11/2)-(-22/3)-(+21/5)-20/3= 16-(-25/3)-(+14/3)
(-11/2)-(-22/3)-(+21/5)-20/3 =(-11/2-21/5)-(-22/3+20/3) =-97/10+2/3 =-271/10 =-27.1 16-(-25/3)-(+14/3) =16+(25/3-14/3) =16+11/3 =19又2/3
(-11/2)-(-22/3)-(+21/5)-20/3= 16-(-25/3)-(+14/3)
(-66)*【1又22分之21-(3分之1)+(-11分之5)】
-11+22-(-3)*11只要答案
1、-22/7*(22/7—22/3)*7/22*21/22(计算过程)
找规律.1,2,3,5,8,13,21,( ),( )…… 1,2,4,7,11,16,22,29,( )找规律.1,2,3,5,8,13,21,( ),( )…… 1,2,4,7,11,16,22,29,( ),( )……

计算-22/7*(22/7-4/3)*7/22*(-21/22)
1:2 、 5 、 11 、 22 、 32 ( ) 65 、 86 2:10 、20 、21 、42 、43 ( ) 、 ( ) 、174请说明规律性
简便计算:1/3+(3/4-2/3)除以1/5 = 1-6/11除以21/22-3/7 =简便计算:1/3+(3/4-2/3)除以1/5=1-6/11除以21/22-3/7=,
1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19+20+21+22+23+24等于( )
(27+2x)(21 -4x )=3/4*27*21;(22+2x)(29+2x )-22*29=1/4*22*29要详细过程
