125X(33X8)简便计算

(125*8)*33=33000

用简便方法计算 125x34x8 =(125×8)×34 =1000×34 =34000

125x(8+35) =125x8+125x35 =1000+4375 =5375

=68x(125X8)=68x1000=68000

(125+7)x8简便运算 =125×8+7×8 =1000+56 =1056。

=125×8—40×8 =1000—320 =680

=125*8*89=1000*89=89000

125x(47x8) =125x8x47 =1000x47 =47000

125x8.88 =125x8x1.11 =1000x1.11 =1110

125x8-30x8 =1000-240 =760 如有帮助请采纳, 如对本题有疑问可追问,Good luck!
