48×87怎么列竖式计算?
一位对着一位先用48×7,再加上48×80,这个比较难,要验算用得数来除以87或除以48都是可以的,看看能不能等于48或87,如果没办法等于,那就说明你算的是错的如果。如果等于,那就说明你算的是对的,就是这么简单
48×48等于多少,用竖式计算?
您好!48乘以48等于2304,数学式子为48×48=2304,乘法竖式运算如下图所示。
拓展资料:
竖式,指的是每一个过渡数都是由上一个过渡数变化而后,上一个过渡数的个位数乘以2,如果需要进位,则往前面进1,然后个位升十位,以此类推,而个位上补上新的运算数字。竖式是指在计算过程中列一道竖着的式子,使计算简便。
乘法竖式运算是指一个数的第1位乘上另一个数的第1位就应加在积的第i+j-1位上。至于你说的“过了10 ”是没关系的,直接向上面进位就行了。

498÷8?列竖式并验算
498÷8=62......2,竖式如下
竖式图片:
验算:
商*除数+余数=被除数。
62*8+2=498
解题:
1、首先,把除数498、被除数8、竖式除号写出来,再从最高位开始除。
2、498的最高位是百位,则从百位上开始除起。
3、百位上:4÷8不够除,按其运算法则,与下一数位的9合成49。商6余1,因为百位数不够除,商数直接写在十位数上。
4、个位上8,与余数1合成18与8相除,商2余数为2,在个位上写2.最下面写上余数2
得出算式:498÷8=62......2,
扩展资料:
除法运算公式
被除数÷除数=商
例:
被除数÷商=除数
例:
→
商 除数=被除数 例:
还有一种情况:
被除数÷除数=商......(六点)余数(不大于除数)
除数×商+余数=被除数
运算性质
被除数扩大(缩小)n倍,除数不变,商也相应的扩大(缩小)n倍。
除数扩大(缩小)n倍,被除数不变,商相应的缩小(扩大)n倍。
被除数连续除以两个除数,等于除以这两个除数之积。有时可以根据除法的性质来进行简便运算。如:300÷25÷4=300÷(25×4)除以一个数就=这个数的倒数
488除以4等于多少的列竖式计算怎么列
488除以4等于122,列竖式如下:
408÷48等于多少?竖式计算
这个题目可以用除法竖式进行计算,先从被除数的高位除起,除数有几位,就看被除数的前几位,如果不够除,就多看一位。除到被除数的哪一位,就把商写在哪一位的上面,如果不够除,就在这一位上商0。除得的余数必须比除数小,并在余数右边一位落下被除数在这一位上的数。”具体计算过程如下:
望采纳,谢谢。
