+Compute the [Root mean square](https://en.wikipedia.org/wiki/Root mean square "wp: Root mean square") of the numbers 1 through 10 inclusive.
+
+The *root mean square* is also known by its initials RMS (or rms), and as the **quadratic mean**.
+
+The RMS is calculated as the mean of the squares of the numbers, square-rooted:
+
+$$x\_{\\mathrm{rms}} = \\sqrt {{{x_1}^2 + {x_2}^2 + \\cdots + {x_n}^2} \\over n}. $$

-`rms`是一个功能。
+`rms` should be a function.
 
 ```js
 assert(typeof rms === 'function');
 ```
 
-`rms([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])`应等于`6.2048368229954285` 。
+`rms([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])` should equal `6.2048368229954285`.
 
 ```js
 assert.equal(rms(arr1), answer1);
