What is The X•Y Chart™?
The X•Y Chart™ is a colorful picture of mathematics. It shows the 10 by 10 multiplication facts in their natural environment, a table of rows and columns cornered in the first quadrant of the rectangular coordinate system.
The bright primary colors of the quadrants signal a change of sign, a positive-negative switch, inviting the observer to continue beyond the borders of the chart toward the limiting infinities.
