Hi, Thanks for playing. The order in the game starts from left to right(1°+2°-3°X4°).
I heard that starting with multiplication would be correct in mathematical logic, but I skipped some school days so I probably lost that one (sorry about that).
It has to give you a 2 digits code. But for achieving you have to calculate each one in order, as RED + BLUE, the RESULT - YELLOW, the next result * 9.
