###  Problem Explanation:
|
||
|
|
|
||
|
|
The algorithm to convert from Celsius to Fahrenheit is the temperature in Celsius times `9/5`, plus `32`.
|
||
|
|
|
||
|
|
You are given a variable **celsius** representing a temperature in Celsius. Use the variable **fahrenheit** already defined and apply the algorithm to assign it the corresponding temperature in Fahrenheit.

##  Hint: 1
|
||
|
|
|
||
|
|
Take a look at the code. There is an area that you're not supposed to edit. From there, ask yourself - what is used there that I haven't seen before?

**Solution ahead!**
|
||
|
|
|
||
|
|
##  Basic Code Solution:
|
||
|
|
```javascript
|
||
|
|
function convertToF(celsius) {
|
||
|
|
// Only change code below this line
|
||
|
|
var fahrenheit = (celsius * (9/5)) + 32;
|
||
|
|
|
||
|
|
// Only change code above this line
|
||
|
|
if ( typeof fahrenheit !== 'undefined' ) {
|
||
|
|
return fahrenheit;
|
||
|
|
} else {
|
||
|
|
return 'fahrenheit not defined';
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
// Change the inputs below to test your code
|
||
|
|
convertToF(30);
|
||
|
|
```
|
||
|
|
### Code Explanation:
|
||
|
|
|
||
|
|
* Declare the **fahrenheit** variable.
|
||
|
|
* Make sure the proper order of arithmetic operations is followed by using parenthesis (`()`) when needed.
