There’s a magic square. Note that you can type numbers or letters into the magic 
square, but only one digit. 

There are only two numbers in the puzzle.

To solve the puzzle, you’re supposed to think like a Roman. Since 19 is prime, 
the square must be solved using addition. Since only one digit fits and the 
largest digit must be at least a 10, this can’t be solved using conventional
digits.

A Roman would note that 3 Xs is 30. And XIX is 19. 
So fill the square with 8 Xs surrounding an I. 
Press the lever and obtain a key.

Go up, under the desk.
Use the key to open a drawer and obtain a key chain with a remote. 
Go back three times.

Place the four coins in the remote. 
Note that when you press remote buttons, the red light on the top of the remote blinks.
Press the center OK button on the remote. 
Congratulations, you escaped.
