这是一个四则运算的应用,即指加法、减法、乘法和除法四种运算。四则运算是小学数学的重要内容,也是学习其它各有关知识的基础。
运算关系
乘法是加法的简便运算,除法是减法的简便运算。
减法与加法互为逆运算,除法与乘法互为逆运算。
加数+加数=和
被减数-减数=差
一个加数=和-另一个加数
减数=被减数-差
被减数=差+减数
因数×因数=积
一个因数=积÷另一个因数
被除数÷除数=商
除数=被除数÷商
被除数=商×除数
主要功能
①应用自动随机生成四则运算题
②做题道数可以自行设置,从10-100可设
③每道题倒计时30秒,时间到即为做题失败
④实时显示目前在做题数和做对题数
⑤题目做完应用自动判定对错,将题目、正确答案、玩家回答答案一并列表展示
⑥点击错题可以选择添加到错题集,方便下次再做
⑦快速算术,检测您的基本数学和反应能力
