Practicising mental arithmetic can sharpen up your thinking ability by making use of one of the most powerful computers in the world - i.e. the one between your ears!
In order to become a Math Mind Wizard, it is recommended that this application is used as follows:
Master the multiplication times tables
Study the Mental Arithmetic Tips
Practice the Training Exercises
Take the Math Mind Challenge
There are 12 levels in the Math Mind Challenge - each set of mental calculations contains 10 questions - answer all questions correctly and proceed to the next level - if 9 are answered correctly will remain at the current level - answering less than 9 correctly causes a drop in level - how quickly can you get to level 12? - how long can you stay there? - a full history is provided showing your attempts at each level.
This is an ad-supported app - an ad-free paid version is also available for a nominal USD 0.99 but, as always, it's probably best to test the free version first before parting with your hard-earned cash :) - to download, please search for Math Mind (adfree)
