TinyMath

TinyMath improves your computation and concentration skills
by giving you a sequence of mathematical equations.
Find the INCORRECT one !

example sequence from the application logo (8*7 has been computed incorrectly) :

2*7=14 3*7=21
4*7=28 5*7=35
6*7=42 7*7=49
8*7=55 9*7=63

You can select whether you want to have a regular 9*9 layout of the equation sequence
or a 4*21 layout that better fits the screen (and is a bit more nerve-consuming to solve).

If desired you can switch to a classic math tutor where tasks like

21 : 7 = ? , 18 - 9 = ? , 8 * 5 = ? , 9 + 9 = ?

5/4 + 13/4 = ?/2 , 2/5 * 4/5 = ?/25

7% of 200 = ?

have to be computed sequentially.

Optionally selectable interactive help for multiplications of 2 multi-digit numbers is provided:
tapping at a line explains how the number for that line has been computed.
