【實用教育app】Simple Math Flashcards Free|最夯免費app-綠色工廠好玩App

This is the free version of Simple Math Flashcards, the app that is like having a deck of flashcards wherever you go. This free version is limited to addition and subtraction, and the easy (numbers 1-5) and intermediate (0-9) levels. Upgrade to the full version for these additional features:* Choose from addition, subtraction, multiplication, division, or any combination of the four. * Choose from three difficulty levels: easy (numbers 1-5), intermediate (0-9), or advanced (0-12). All three difficulty levels are included.* Use the whole deck, or limit the deck to problems involving a certain number. This feature comes in handy when, for example, you need to work on multiplication by nines.
