小学生快速口算技巧及练习

快速口算技巧及练习 一、个位是1的两位数相乘 方法:十位与十位相乘,得数为前积,十位与十位相加,得数接着写,满十进一,在最后添上1。 例:51 × 31 50 × 30 = 1500 50 + 30 = 80 ------------------ 1580+1=1581 因为1 × 1 = 1 ,所以后一位一定是1,在得数的后面添上1,即1581。数字“0”在不熟练的时候作为助记符,熟练后就可以不使用了。 二、头同尾不同两位数相乘 被乘数加上乘数个位,和与十位数整数相乘,积作为前积,个位数与个位数相乘作为后积加上去。 例:43 × 46 (43 + 6)× 40 = 1960 3 × 6 = 18 ---------------------- 1978 三、头同尾和10的两位数相乘 十位数加1,得出的和与十位数相乘,得数为前积,个位数相乘,得数为后积,没有十位用0补。 例:56 × 54 (5 + 1) × 5 = 30-- 6 × 4 = 24 ---------------------- 3024 四、头同,尾和不为10 两首位相乘(即求首位的平方),得数作为前积,两尾数的和与首位相乘,得数作为中积,满十进一,两尾数相乘,得数作为后积。 例:56 × 58 5 × 5 = 25-- (6 + 8 )× 5 = 7-- 6 × 8 = 48 ---------------------- 3248 得数的排序是右对齐,即向个位对齐。这个原则很重要。 五、被乘数首尾相同,乘数首尾和是10的两位数相乘。 乘数首位加1,得出的和与被乘数首位相乘,得数为前积,两尾数相乘,得数为后积,没有十位用0补。 例:66 × 37 (3 + 1)× 6 = 24-- 6 × 7 = 42
