【實用教育app】MemSum|最夯免費app-綠色工廠好玩App

MemSum is an educational mental arithmetic game designed to improve anyone's mathematics skills and exercise their short term memory.

The player must solve successive addition and subtraction operations built upon the results of previous sums. As the game progresses, the player must recall the result of previously solved problems and use this to solve the current math operation. At higher difficulty levels, the results of three sum operations must be remembered simultaneously. The difficulty of the sums ranges from adding and subtracting values less than 10, to including negative numbers, to multiples of 10 including two decimal places.

MemSum is suitable for all ages.
