The root of mathematical study is to consider different perspectives, manipulate visuals, find patterns, and use reason and logic to better understand our natural world.

Thinking mathematically helps one to examine, analyze, and solve life's problems in an organized logical manner. Understanding mathematical concepts allows us to perceive, interpret, critique, and transform the world.
