数学术语英文
数学术语英文在我们学习数学的过程中，会遇到各种各样的术语。
而当我们需要与国际上的数学领域进行交流，或者阅读国外的数学资料时，了解这些数学术语的英文表述就变得非常重要。
首先，让我们从最基础的数字和运算开始。
“零”在英文中是“zero”，“一”是“one”，“二”是“two”，以此类推。
而常见的运算符号，“加”是“plus”或者“add”，对应的加法算式可以表述为“One plus two equals three”（一加二等于三）。
“减”是“minus”或者“subtract”，例如“Five minus three is two”（五减三等于二）。
“乘”可以用“multiply”或者“times”，像“Two times three equals six”（二乘三等于六）。
“除”则是“divide”，比如“Six divided by two is three”（六除以二等于三）。
接下来是几何图形方面的术语。
“三角形”是“triangle”，“正方形”是“square”，“长方形”是“rectangle”，“圆形”是“circle”，“椭圆形”是“oval”，“菱形”是“rhombus”。
在描述图形的性质时，“边长”是“side length”，“周长”是“perimeter”，“面积”是“area”。
再看看代数领域。
“未知数”通常用“unknown”或者“variable”表示。
“方程”是“equation”，例如线性方程“linear equation”。
“函数”是“function”，像常见的一次函数“linear function”，二次函数“quadratic function”。
“系数”是“coefficient”，“常数”是“constant”。
在统计学中，“平均数”是“average”或者“mean”，“中位数”是“median”，“众数”是“mode”。
“概率”是“probability”，“随机变量”是“random variable”。
