Functions are used throughout mathematics and have applications in many disciplines.  However, we are often interested in finding the extreme values, such as function maximums. So, what do...

Area and circumference of a circle both involve the constant π and the radius of the circle, but their units vary. So, how are the circumference and area of a circle related?  The...

Box plots are used often in statistics to give a visual summary of a data set.  However, this still raises the question of what exactly they reveal, and what we can calculate from what we are...

Exponential functions are found often in mathematics and in nature.  However, this still raises the question of what these functions are and what they look like. An exponential function is...

FOIL and the Distributive Property are both used often in mathematics, starting in Algebra.  However, one stems from the other, and it is important to know when to use each one. So, what is...

Standard deviation is used in statistics to tell us how “spread out” the data points are.  Having one or more data points far away from the mean indicates a large spread – but there are...
