50以内的加减法和连乘法混合口算题
50以内的加减法和连乘法混合口算题
在数学的学习中,口算能力是一项非常重要的基础技能。50 以内的加减法和连乘法混合口算题对于小朋友们来说,是锻炼思维敏捷性和计算准确性的有效方式。
先来说说 50 以内的加法口算题。比如 23 + 15 ,我们可以先把个位上的数字相加,3 + 5 = 8 ,然后再把十位上的数字相加,20 + 10
= 30 ,最后把两个结果相加,30 + 8 = 38 。再比如 18 + 21 ,个位相加 8 + 1 = 9 ,十位相加 10 + 20 = 30 ,总和就是 39 。
减法口算题也有它的小窍门。像 45 18 ,个位上 5 不够减 8 ,就从十位借 1 当 10 ,15 8 = 7 ,十位上 4 借走 1 还剩 3 ,3 1 = 2 ,所以结果是 27 。又如 32 17 ,个位 2 不够减 7 ,从十位借 1 ,12 7 = 5 ,十位 3 借走 1 剩 2 ,2 1 = 1 ,答案就是 15 。
接下来是连乘法。比如 2 × 3 × 4 ,我们先计算 2 × 3 = 6 ,然后 6 ×
4 = 24 。再看 3 × 4 × 5 ,3 × 4 = 12 ,12 × 5 = 60 。
下面给大家出一些混合口算题来练练手:
1、 12 + 18 5 ,先算加法 12 + 18 = 30 ,再算减法 30 5 = 25 。
2、 20 15 + 8 ,先算减法 20 15 = 5 ,再算加法 5 + 8 = 13 。
3、 3 × 2 + 10 ,先算乘法 3 × 2 = 6 ,再算加法 6 + 10 = 16 。
4、 15 4 × 2 ,先算乘法 4 × 2 = 8 ,再算减法 15 8 = 7 。 5、 2 × 3 × 2 + 7 ,先算连乘 2 × 3 × 2 = 12 ,再算加法 12 + 7 =
19 。
6、 18 3 × 3 ,先算乘法 3 × 3 = 9 ,再算减法 18 9 = 9 。
