这是一个题还是俩题啊
3/10×1/4×5/9 算式
计算下面各题能简算的要简算 5/6-1/2+1/4 5/12+3/4-5/8 4/5-(3/10+1/6) 5/9+7/18+4/9 1-2/7-5/72/3+5/13+1/3
(-4/9)+(+4/5)-(+5/6)-(+9/10)-(-1又5/18
(-4/9)+(+4/5)-(+5/6)-(+9/10)-(1又5/18) (+11)+(-1/2)+(+7)+(-1/6)+(+2)+(-1/3)
8/9-3/8+1/9 7/9-2/5-5/18 5/12+3/4+2/3 1/2+(2/3-1/4) 1-1/8-3/10 5/6-(1/2-1/3)计算要有过程
1+2+3+4+5+6+7+8+9+10+18
1+2+3+4+5+6+7+8+9+10+12+14+16+18+20=?

|1/3-1/2|+|1/4-1/3|+|1/5-1/4|+...+|1/10-1/9|
5/18 x 1/4 x 9/10 ( 1/4 + 2/9 )x 36 7/11 x 3/8 x 4/9 简便计算哈~
