## What is Base X?

Base X is a fun way to learn math and it is ready for action in all kinds of places! Great for learning at home, a great teaching aid for home schooling parents, schools, libraries or even on long road trips!

Touch on one of the number squares along the bottom row and the corresponding brick will appear above it.

Drag the brick to move it onto the work area. You can drag as many bricks as you like one at a time.

To remove a brick, simply drag it into the recycle can. If you want to clear the work area completely, touch the reset button at the top right of the screen.

Use Base X to learn to count by 2's, 3's, 4's, 5's, 6's, 7's, 8's, 9's, 10's.

Easy to use and very handy, especially if you forget to bring the physical bricks with you.

The bricks are easy to count whether adding or subtracting.

Perfect for little fingers to manipulate.
