如何运用0—9全部10个数字组成一个三位数加三位数等于四位数的加法算式,而且每个数字不能重复使用!2+7=93+5=84+6=10故:432+657=1089423+675=1098437+652=1089473+625=1098452+637=1089425+673=1098457+632=1089475+623=1098632+457=1089623+475=1098637+452=1089673+425=1098652+437=1089625+473=1098657+432=1089675+423=1098
用数字0,1,2,3,4,5,6,7,8,9,列一个三位数加三位数等于四位数的加法竖式,数字不能重复使用自己改成竖式就可以了437 + 589 = 1026246 + 789 = 1035324 + 765 = 1089
用0至9这九个数字,组成一道加法算式。要求是三位数加上三位数等于一个四位数。“liulei20010113”:您好。共有96个算式:246+789=1035,249+786=1035,264+789=1053,269+784=1053,284+769=1053286+749=1035,289+746=1035,289+764=1053,324+765=1089,325+764=1089342+756=1098,346+752=1098,347+859=1206,349+857=1206,352+746=1098356+742=1098,357+849=1206,359+847=1206,364+725=1089,365+724=1089423+675=1098,425+673=1098,426+879=1305,429+876=1305,432+657=1089437+589=1026,437+652=1089,439+587=1026,452+637=1089,457+632=1089473+589=1062,473+625=1098,475+623=1098,476+829=1305,479+583=1062479+826=1305,483+579=1062,487+539=1026,489+537=1026,489+573=1062537+489=1026,539+487=1026,573+489=1062,579+483=1062,583+479=1062587+439=1026,589+437=1026,589+473=1062,623+475=1098,624+879=1503625+473=1098,629+874=1503,632+457=1089,637+452=1089,652+437=1089657+432=1089,673+425=1098,674+829=1503,675+423=1098,679+824=1503724+365=1089,725+364=1089,742+356=1098,743+859=1602,746+289=1035746+352=1098,749+286=1035,749+853=1602,752+346=1098,753+849=1602756+342=1098,759+843=1602,764+289=1053,764+325=1089,765+324=1089769+284=1053,784+269=1053,786+249=1035,789+246=1035,789+264=1053824+679=1503,826+479=1305,829+476=1305,829+674=1503,843+759=1602847+359=1206,849+357=1206,849+753=1602,853+749=1602,857+349=1206859+347=1206,859+743=1602,874+629=1503,876+429=1305,879+426=1305879+624=1503,你随便抽一个算式检验一下看,对不对。祝好,再见。
用0-9列一个三位数加三位数的竖试加法等于一个四位数,10个数字不能重复用,怎么列342+ 756-------1098
用0.1.2.3.4......9组成一个三位数加三位数结果是四位数的加法算式623+475=1098
用0一9这十个数字组成一个减法竖式 四位数减三位数等于52
用123456789组成一个三位数加三位数的算式 不能重复使用129+438=567428+139=567138+429=567128+439=567182+763=945183+762=945541+386=927
如何把0到9数字组成一个4位数减三位数等于三位数---就是,用0到9这十个数字组成两个三位数相加等于一个四位数的算式因为"两个数相加等于第三个数,且十个数字必须用且只可用一次",所以只能是两个三位数相加等于一个四位数,该四位数的千位上的数字只能是1.再根据加法进位原理,最终可确定该四位数,只能是1206、1035、1503、1062、1089、1098、1206、1305、1503、1602,当四位数是1053或者1089或者1098有成立的三个数各有16个:(324,765,1089),(342,756,1098),...(346,752,1098),(364,725,1089),(724,365,1089),(423,675,1098)......(其它的可类似写出:对前两个数交换个位,交换十位,交换百位)当四位数是1206有成立的三个数10个:(359,847,1206),(349,857,1026),(847,359,1026),(357,849,1026)......当四位数是1035或者1062或者1305或者1602有成立的三个数各有8个,用相同的道理可以推出。487+539=1026,489+537=1026,537+489=1026,539+487=1026,587+439=1026,589+437=1026 (6)246+789=1035,249+786=1035,286+749=1035,289+746=1035,746+289=1035,749+286=1035,786+249=1035,789+246=1035 (8)264+789=1053,269+784=1053,284+769=1053 ,289+764=1053,769+284=1053,
