I understand why some got 2212. This is because you calculated it the same way we do subtraction.
18630 0 cannot divide 8 so you borrow 1
16418 10 - 8 = 2
---------
2212
But that's a wrong calculation
The question showed base 9 not base 10
18630 0 cannot divide 8 so you borrow 1
16418 The 1 you borrowed is 9 NOT 10
--------- 9 - 8 = 1
2211

I also got 2212
we're supposed to convert it to base 10 first then subtract after that we convert back to base 9 not directly subtracting it
even chat GBT at first said it was 2211 cause it was subtracting directly but after I showed it my
workings it confirmed that it was
correct

most of you saying the answer is 2212 did your calculations in base ten
we were asked to subtract in base 9
