I think the (3, 3)th element is -2

yeaa, i also got -2

I checked if that's the inverse but it founds that R2 will not become 0 1 0 because when we multiply R2 which 0 -2 1 from column 3 which 1 -1 2, the answer will be 0 1 4 .. so I think there is something wrong in the solution.

I am pretty sure all of the math is correct. I did make one tiny writing error at 11:11 when I wrote the bottom row. It should be -4 5 -2 like I had written previously. I suppose I forgot the - on the 2 in the end. Oops!
