As a reviewer pointed out, version 1.1 was very buggy. Update to get the fixed version.
This app allows you to easily learn and practice mental math, from the basics (2 digit + 2 digit multiplication addition) up to 3 digit squares!
-up to 3 digit + 3 digit addition and 3 digit 3 digit subtraction.
-up to 3 digit / 1 digit division.
-up to 2 digit * 2 digit multiplication.
-up to 3 digit squares.
And these are all interactive!
If you want more math, go get Mental Mathematics Paid (just released) for everything up to 5 digit numbers squared (Addition, subtraction, and division are not released yet.).
