\text{Paranormal Day}

===

Today (May 2) is Paranormal Day! A day to "celebrate?" all those unexplained phenomena, those bumps in the night, and your keys, which you could have sworn you put in the bowl by the door but are somehow now on the kitchen counter.

You're investigating some paranormal activity in an old spooky house. Don't worry though, you have your trusty Ghost-Expiiliminator $3000$ which can zap ghosts away. Well, maybe you should worry a little because it's your first day on the job.

The Ghost-Expiiliminator $3000$ is a confusing device that requires some ghostly calculations before using. Being a math superstar though, you came up with an easy way to remember how to adjust the laser.

Phantom Range $\Leftrightarrow$ Parentheses
Ectoplasm Level $\Leftrightarrow$ Exponential
Multi-dimensional Level $\Leftrightarrow$ Multiplication
Danger Level $\Leftrightarrow$ Division
Agression Level $\Leftrightarrow$ Addition
Spookiness Level $\Leftrightarrow$ Subtraction

Once calculated, all you need to do is set the laser to that number and fire.

As you make your way into the cellar, a ghost appears. Upon first glance you judge that the ghost is of a $2^{\text{nd}}$ multi-dimensional level, with a phantom range containing $11$ and its spookiness level of $3$ , a danger level of $4$ with an ectoplasm level of $2$ and an aggression level of $9$ .
