和sum,差difference,积product,商ratio1+2:One plus two.1-2:One minus two.1*2:One multiplied by two.1/2:One over two/One divided by two./:读作solidus或diagonal,÷读作obelus
和。。。 有三种表示法: 1)and 用于肯定句, 例如You and me,你和我~~~2) or 英语否定句 No eating or drinking in the class. 班级里不许吃东西和喝饮料。 3) with也表示和...但是它主要表示一种伴随的状态,如 the girl with her mom goes to the park. 女孩和妈妈一起去了公园。 谢谢采纳~~
and或者with,with的和一般放在句尾,比如“i went to a park with him yesterday. ”(昨天我和他去了一个公园。)and放句头,“he and me went to a park yesterday.”(昨天我和他去了一个公园。)意思好像差不多。希望对你有帮助。
