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.
