From your information, I don't see an error. May the error is asking you to describe one.
Answered by Annie
wait. are the brackets around the numbers saying to find their absolute value, or is that just ot separate them?
Answered by PsyDAG
Absolute numbers are not indicated by brackets "[]" but by straight lines "II".

I-13I - I13I = 0

(The vertical lines should be longer, but I don't know how to print them on the computer.)
Answered by ann
