In this project, you’ll be honing your knowledge of arithmetic operations, augmented assignment operators, and more by coding a mathematical magic trick.

Within the `main()` function, declare an immutable variable, `userName`, and assign it a String value of your name. 





Next, declare a mutable variable, `magicNum`, to hold a value of type, `Int`. Don't initialize the variable with a value just yet; we will do that in the next step. 

Now that we've declared all the variables we'll need in this program, we're ready to start coding our magic trick. 

The first step is to multiply the first digit of your age by `5` and assign this operation to `magicNum`.  

Next, add `3` to the value of `magicNum`. 

On the following line, multiply the value of `magicNum` by `2` and reassign the result back to `magicNum`. 

Add the second digit of your age to `magicNum` and reassign this new value to `magicNum`.

Finally, subtract `6` from `magicNum` and reassign this new value back to `magicNum`. 

On the following line, wrap `magicNum` in a `println()` statement that outputs: 

```
[name]'s age is [magicNum].
```

Awesome work, Mathemagician 🔮 You’ve utilized your knowledge of arithmetic operators and previous fundamental Kotlin concepts to program a magic trick.

- Run your program several times with different age digits and observe the different values on the right. 
- Add a comment to the top of your code to explain to other developers what your program is doing.
