An Interesting App:
I′ve recently downloaded the app called
′Math Tricks′ from the Google Play Store.
If you′d like to improve your speed
and skill in the mental calculations
arena, I think this app should be of
interest to you. The app can throw you simple
calculations that include the basic operations
of addition,subtraction,division and
multiplication. The application can
show you tricks to calculating 52^2 or
125^2 ,for example, under 10 seconds
mentally. So, check it out! I′ve seen
that the levels of difficulty on the
app can go as high as mentally calculating positive
integers raised to the power of 9,
and also finding 9th roots of
positive integers!
