I'm doing a grid, and each square will TAKEAWAY a number from an overall total (in this case, 50). So, for example, square one will takeaway / subtract just one number (making it 49). The next will takeaway / subtract two (making it 47), and so long, until we reach 0.

My current layout is that I have a trigger zone on a square, and this trigger zone is connected to a counter. The counter is then threaded to takeaway/subtract gadget, which is then threaded to a number displayer.

In layman's terms, the trigger zone will trigger the counter to move up one, which is then taken away straight afterwards, making it 49 (and not 51, which it would do if it weren't for the subtract gadget).

There are two problems: one, I am absolutely atrocious at maths, and two, I want the trigger zone to make the counter take away two numbers, not just one.

I don't know how else I can do this, so I feel that I *need* the trigger zone to register a move, but I cannot find a way to have it outpost two moves and not just one.

TLDR; I want to have squares on a grid take away more than one number from a total amount. IE:

Square one - 1 number from 50
Square two - 3 away from 50
Square seven - 8 away from 50


Anyone have any ideas? I've tried to make this as simple as possible, and in theory it is, but I can't figure it out.
