Bugs in Subtraction – Rocket Math Addition Review

Good app, fun for our 1st grader. Easy to navigate and visually appealing. All the addition levels work fine, but there are bugs in subtraction. The correct answer gets a wrong prompt. It will only accept an addition answer. Ex 8-2 will not accept 6, but will accept 10. Fix that and it's a 5 star.
