第一讲:计算与解方程知识要点:在小学计算题中有好多题型方法新颖独特,在升重点中学考试和进入中学分班考试中,多有出现,有的学生因为没见过这种题型常常得分很少或得零分,其实这种题型只要掌握一定的解题方法和规律一点都不难。
下面老师跟你支支招: 1、熟记规律,常能化难为易。
① 25×4=100, ②125×8=1000,③41=0.25=25%, ④43=0.75=75%, ⑤81=0.125=12.5%, ⑥83=0.375=37.5%, ⑦85=0.625=62.5%,⑧87=0.875=87.5% 2、简便运算一般有三种方法:1. 凑整法:通过加、减一个数将其凑成整十、整百、整千的数。
2. 交置法:也即通常所说的结合律,几个数相加、相减,将其位置交换一下,凑成整十、整百、整千的数。
3. 去括号法:有时在计算含有括号的算式时,通过去除括号,可使运算简便,但要注意的是去括号后的符号变化。
