How to solve a quest in Warehouse on Nar Shadaa

Some of the gamers stucks at quest when you play as T3-M4 in Warehouse of Nar Shadaa. The terminal wants you to solve some math quiz, but of course not all of us strong in logical tests (me too). But pushing Google to find a salvation takes much time, that's Steam Guides are made for!

The code that you have to get matching is this one:
3E1D
L7T3

And you have to make it look like this:
1E7T
3L3D

All you need to do is to click following buttons:
1 - rotate center block counter-clockwise
2 - rotate left-most block counter-clockwise
3 - rotate right-most block clockwise

That is all you need to do, the door will open.

Good luck and have a good day!
