Tried it a few other times and it seems to sometimes like giving something that results in 3^5 (which would be 243 on its own) followed by subtracting a bit from it, which ends up making it the wrong answer. In the link above, it basically goes (3^5) - (8 - (1 - 1)), so if you only keep the first brackets it would be correct.
I tried punching in 243 and it gave me an equation that resolves to 235.
