## Smooth Operator

### Math Operators
|
||
|
|
|
||
|
|
They are other operators than assignation, for now let's focus on the one you
|
||
|
|
probably already know:
|
||
|
|
|
||
|
|
- `+` Addition
|
||
|
|
- `-` Substraction
|
||
|
|
- `/` Division
|
||
|
|
- `*` Multiplication
|
||
|
|
|
||
|
|
Those operators are used the same way we would write them in math:
|
||
|
|
|
||
|
|
```js
|
||
|
|
console.log(5 + 7) // -> 12
|
||
|
|
console.log(5 * 5) // -> 25
|
||
|
|
console.log(7 - 5) // -> 2
|
||
|
|
console.log(9 / 3) // -> 3
|
||
|
|
```
|
||
|
|
|
||
|
|
Operators are evaluated using classic priority:
|
||
|
|
|
||
|
|
```js
|
||
|
|
console.log(1 + 5 * 10) // -> 51
|
||
|
|
```
|
||
|
|
|
||
|
|
you can use parens `()` to enforce priority:
|
||
|
|
|
||
|
|
```js
|
||
|
|
console.log((1 + 5) * 10) // -> 60
|
||
|
|
```
|
||
|
|
|
||
|
|
And they are resulting in a value, as such they can be assigned to variables:
|
||
|
|
|
||
|
|
```js
|
||
|
|
let halfMyAge = 33 / 2
|
||
|
|
let twiceMyAge = 33 * 2
|
||
|
|
```
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Your code must use the given variable `smooth` as our initial value
|
||
|
|
|
||
|
|
You will declare a few variables:
|
||
|
|
|
||
|
|
- `lessSmooth` that is just `1` less than `smooth`
|
||
|
|
- `semiSmooth` that is the half the amount of `smooth` _(it's still pretty
|
||
|
|
smooth)_
|
||
|
|
- `plus11` that is `smooth` plus `11`
|
||
|
|
- `ultraSmooth` that is the square of smooth _(now that's smooth !)_
