加减乘除的运算对小学生来说已经是非常简单，但是最近有很多中小学生接触了一些国际课程之后，就发现英语的表达为什么如此繁多复杂，为了更好地与国际接轨，我们还真得好好得学习下英语的四则运算。况且，这还是初中数词专题必须要掌握的知识点哦！

2 3=? 可表示为：
How much is two plus three?
2 3=5 可表示为
Two plus three is five．
Two and three is equal to five．
Two and three makes five.
Two added to three equals five．
或者 If we add two to/and three, we get five.二加三等于五
一定要看清"加减乘除"的词性，这是表达的关键
减 —“减”： minus（介）或 take from, subtract（动）

Take six from ten and the remainder is four.

乘 ד乘”：times（介词）或multiply（动词）, mutiplied by（分词）
3X4＝?

除 ÷“除”：divide（动词）, divided by （分词）
