Very good but… – Newton - Addition and Subtraction Review

Updated: To the developer – thank you for your response and your hard work on the app. The update with the shorter time makes it spot on terrific. Five stars to you! Original: My kids like playing this game but the time is too long. They want to shorten it to two or three seconds. This would be a simple add into the settings. Please add this feature. The time on the multiplication one is too short. Please make adjustable for kids of all ages. Having said that this is a terrific app. With that one feature I think I would give it a four or a five star. Keep up the good work.
