You'll see when you further into the game :))

You need another item in order to solve the computer puzzle, you can get it by completing the minigame where the shutters are; by out running Nem using Aldan's ability, you can obtain a small key to the Nurse's office and get a USB to use it on the computers to solve the code!

But if you already have the item,  here's a hint; The big red X in the room actually represents a multiplication sign

I'm planning to make a walkthrough soon, so hopefully I can get it out by then :))
