From your information, I don't see an error. May the error is asking you to describe one.

wait. are the brackets around the numbers saying to find their absolute value, or is that just ot separate them?

Absolute numbers are not indicated by brackets "[]" but by straight lines "II".
I13I  I13I = 0
(The vertical lines should be longer, but I don't know how to print them on the computer.)
