Try a Few: Add the Opposite
Change it to adding the opposite. 12 problems, each with help one step at a time.
12 problems
Try each one yourself first. Hint nudges you, Show next step walks it one step at a time, Reveal answer checks, and Hide help / start over clears the card.
Write it down. Do every change on paper, one line per step. Changing signs in your head is the number one reason for missed problems. If you changed something, it should be on the paper.
