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数学运算符 的英文表达
