2月27日的Big Addition: Long Addition应用程序分析

Big Addition can help you improve your problem solving speed and accuracy for multi digit addition problems. If you need a refresher, there is a step-by-step problem solver in the practice area that can read-out the solution to you a step at a time. (Text-to-speech support required.) Larger, more difficult, problems are unlocked by solving smaller/easier problems. You can analyze your problem areas with both numerical and color-coded display of your results. Stay motivated by setting and beating your fastest times. Find your best rhythm by turning off/on any combination of verbal, sound, and vibration feedback. This is a free-to-download, ad-supported app. Thanks for any support. MATH Domain Development
