20以内三位数加减法混合题目

20以内三位数加减法混合题目

《20 以内三位数加减法混合题目》小朋友们,今天咱们来瞧瞧20 以内三位数加减法混合题目。

你们看,这些题目就像一个个小小的挑战,等着聪明的你们去解决呢。

比如说,“125 + 67 - 88 ”,咱们先来算加法,125 加上67 ,个位 5 加7 等于12 ,向十位进 1 ,十位 2 加 6 再加进位的 1 等于9 ,百位还是 1 ,所以125 加67 等于192 ,然后192 减去88 ,个位 2 减8 不够减,向十位借1 当10 ,12 减8 等于 4 ,十位9 被借走 1 变成8 ,8 减8 等于0 ,百位1 不变,结果就是104 。

再看这道“188 - 56 + 34 ”,先算188 减56 ,个位8 减 6 等于 2 ,十位8 减5 等于 3 ,百位 1 不变,就是132 ,然后132 加34 ,个位 2 加 4 等于6 ,十位 3 加 3 等于 6 ,百位 1 不变,结果是166 。

我给你们讲个小故事。

小红在做这种题目的时候,一开始总是做错。

有一次,遇到“157 + 28 - 63 ”,她算成了122 ,结果老师给她指出来错在哪里。

从那以后,小红做题可认真啦,每次都能做对。

咱们再看看这样的题目,“103 - 47 + 78 ”,先算103 减47 ,个位 3 不够减7 ,向十位借 1 ,13 减7 等于 6 ,十位0 被借走 1 变成-1 ,不够减 4 ,向百位借1 ,10 减 1 再减 4 等于 5 ,百位 1 被借走 1 变成0 ,所以103 减47 等于56 ,然后56 加78 ,个位 6 加8 等于14 ,向十位进 1 ,十位5 加7 再加进位的 1 等于13 ,向百位进 1 ,百位是 1 ,结果就是134 。

小朋友们,做这些题的时候,要静下心来,一步一步地算。

就像走小路一样,一步一个脚印,才能稳稳地走到终点。

比如说“118 + 36 - 72 ”,先算加法118 加36 ,得到154 ,再用154 减去72 ,结果是82 。

20以内进位加减法

20以内进位加减法

20以内进位加减法20以内进位加法:方法一:“凑十法”(强调:看大数,分小数,凑成十,加剩数)8+5=8+2+3=13;方法二:“五五凑十”( 当两个加数都大于且接近5时适用) 6+7=5+5+1+2=13;方法三:“多加减补”8+5=10+5-2=13.20以内进位加法“凑十法”、“凑小数,拆大数”,将小数凑成10,然后再计算。

如: 3+9 (3+7=10,9可以分成7和2,10+2=12)凑大数,拆小数”,将大数凑成10,然后再计算。

如: 8+7 (8+2=10,7可以分成2和5,10+5=15)整数加法计算法则:相同数位对齐,从低位加起,哪-一位上的数相加满十,就向前一位进一。

整数减法计算法则:相同数位对齐,从低位加起,哪一位上的数不够减,就从它的前一位退一作十,和本位上的数合并在一起,再减。

20以内加减法

20以内加减法

20以内加减法二十以内的加法和减法是小学阶段数学学习的基础内容之一、下面将分别介绍加法和减法的公式,并给出一些例题供参考。

一、加法公式:在二十以内的加法运算中,可以使用以下公式:1.加法交换律:a+b=b+a交换律是指两个数相加的结果不受顺序的影响。

例如:3+4=7,4+3=72.加法结合律:(a+b)+c=a+(b+c)结合律是指进行多个数相加时,可以先将其中两个数相加,然后再将结果与剩下的数相加,不受括号的位置影响。

例如:(2+3)+4=2+(3+4)=93.加法零元:a+0=a零元是指任何数和0相加,结果仍为原数。

例如:5+0=5二、减法公式:在二十以内的减法运算中,可以使用以下公式:1.减法定义:a-b=c,其中c是满足a=b+c的唯一数。

减法的定义是指将两个数相减得到差值,这个差值是唯一的。

例如:8-3=5,5是满足3+5=8的唯一数。

2.减法的性质:减法的结果不受减数与被减数的顺序影响。

例如:8-3=5,3-8=-5下面是一些加法和减法的例题:例题1:计算以下数的和a)3+7解:3+7=10b)9+2解:9+2=11例题2:交换律和结合律a)4+6+2解:根据结合律,可以先计算4+6,再将结果与2相加:4+6=10,10+2=12b)3+5+2解:根据交换律,可以改变加法的顺序:5+3+2=10例题3:计算以下数的差a)8-3解:减法表示将3从8中减去,得到差值:8-3=5b)9-6解:减法表示将6从9中减去,得到差值:9-6=3例题4:减法的顺序a)3-8解:减法的结果不受减数和被减数的顺序影响,可以将3-8改为8-3:8-3=-5b)7-5解:7-5=2通过以上的公式和例题,我们可以很好地理解和掌握二十以内的加法和减法运算。

可以通过反复练习,提高计算的准确性和速度。
