The expressions on the right side may look like circles, but they can also be interpreted as the lengths (squared) of important line segments inside the rectangle. the way of chinaWebIn mathematics, the absolute value or modulus of a real number x, denoted x , is the non-negative value of x without regard to its sign. Namely, x =x if x is a positive number, and x =-x if x is negative (in which case negating x makes -x positive), and 0 =0. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. the way of chinese characters
