Simply launch the skill and tell Alexa the number you want to work on. She will generate ten subtraction problems using that number. You can also ask for mixed numbers and she will generate random subtraction problems.
After ten problems, Alexa will give you a summary of your results and review any problems that you missed.
To launch, simply say, "Alexa, open Subtraction Tutor."
