67x67-34x34+67+34怎么算
67x67-34x34+67+34简便算法 -
=67x67+67-34x34+34 =67x(67+1)-34x(34-1)=67×68-34×33 =134×34-34×33 =34×(134-33)=34×101 =3434
67x67+34x34+67+34简便算法=67x（67+1）34x（34+1）67x68+34x35 =35x（67x2+35）35x（134+35）35x169 =35x200-35x31 =7000-1085 =5915
=67x67+67-34x34+34 =67x(67+1)-34x(34-1)=67×68-34×33 =134×34-34×33 =34×(134-33)=34×101 =3434
67x67+34x34+67+34简便算法=67x（67+1）34x（34+1）67x68+34x35 =35x（67x2+35）35x（134+35）35x169 =35x200-35x31 =7000-1085 =5915
验算2278÷34=67 或34×67=2278
34ⅹ34表示有34个34，34x67表示有67个34，那么一共有(34+67)个34，而算式中间减去一个34，那么就是(34-1+67)个34，列式34x(34-1+67)。
67x234-34x67= -
（234减34）乘67

求34x67+34x34—34的简便算法?谢谢! -
34x67+34x34—34 =34x（67+34-1）34x100 =3400
67×34+67×66 =67×(34+66)=67×100 =6700 如果不懂，请追问，祝学习愉快！
67×54-54×33怎么用简算方式计算 -
67x54-54x33 =(67-33)x54 =34x54 =1836 很高兴为你解答，希望能帮到你！
34X34－34＋34X67 =34*（34-1+67）34*100=3400
