Answer 1

Based on the fact that they jumped from that step to the next, it would appear that they probably don't want you to work out the steps.
It's likely just one they want you to memorize.

We can do the steps if you want.
It's not too difficult, it's just not something that would be obvious and you would recognize on your own. It's a weird multiplication + u-sub.
