# 132Add Two Numbers with JavaScript（加法运算）

最后更新时间：2017年7月28日09:32:06

说明：

```
现在让我们来尝试在JavaScript中做加法运算。

JavaScript 中使用 + 号来让两个数字执行加法运算。

举例

myVar = 5 + 10; // 等于 15
任务
改变数字 0 让变量 sum 的值为 20.

sum 应该等于 20
要使用 + 运算符
```

原始代码：

```
var sum = 10 + 0;
```

调试代码：

```
var sum = 20 + 0;
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://iexam.gitbook.io/fcc/ji-chu/add-two-numbers-with-javascript.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
