What's the console

Hi, I'm wondering what the Elten console is for. I don't know any commands I could enter here.

plum
stuff like 1+2, 2-1, 2/0.5, 2*9
and something I forgot, you can achive it with control shift alt p anyways.

Oh no, not the piano.

Oh yes, the piano, he-he!

it's ruby interpreter console.

except the piano is a xylophone xd

and you can do this
1+2-1/0.5*9+4+1+2+3+3+5+7+5+3+1+0-5+2*2*200+0.908+23145167
