1. ## Limit calculation

In the image below, how am I applying the limit laws wrong? I know the correct solution is 5, but I get -1!

The problem I am facing is something related to my usage of the product rule for limits.

Your limits are absolutely correct. But you middle school arithmetic is lousy.

$\displaystyle 3\cdot 1-1+3=5$

=5
