各种数学符号的英文表达

“加减乘除”怎么说？各种数学符号的英文表达，看完学渣变学霸！不知大家还记得当年所画过的函数图吗？不停地标点，画线，有时候为了画出好看的弧度，甚至要多擦几遍才能做到...每一条函数都有不一样的形状，把它们组合起来，也许会有意想不到的效果噢数学，相信对于不少人，特别是文科班女生的来说，都是一个大难题。在考试时，靠的就是自己的英语来拉分。那么，想要用英语来说出数学公式，又该怎么表达呢？

一. 首先区分一下Equations 和Formulas的使用 1. An equation等式 says that two things are equal. It will have an equals sign "=" like this: x + 2 = 6 2. A formula公式 is a special type of equation that shows the relationship between different variables. 也是一种特殊的等式，只不过展示的是不同变量之间的关系举个栗子：我们常用到的长方体的体积等于长X宽X高就是一个formula V = lwh V stands for volume, l for length, w for width, and h for height. 3. Algebra代数不用多说，就是XY未知数，多年实战，你们懂的

二. 符号要说公式，总不能只说个字母就完事吧，加减乘除先来一翻1.加号+ plus x + 1：x plus one 2.减号- minus x -1：x minus one 3.乘号x multiplied by x times y; x multiplied by y 4.除号÷ over; divided by x over y; x divided by y; 除了这些小学的算术题外，还有这些 1.约等于x ≈ y x is approximately equal to y 2.大于等于x ≥ y x is greater than or equal to y 3.小于等于x ≤ y x is less than or equal to y
