We’ve found the most reliable, usable calculators for pre-algebra, college entrance exams, and university-bound math students.

In the local area (-6 < x < 6) shown at left, the graphs of y = x² + 5 and y = x² are clearly different. But zooming out (at right), the graphs of the two functions are basically identical.
