I’ll be introducing Absolute Value.

Unconsciously Incompetent: I can start at zero and count how far away it is.

Consciously Incompetent: I know there’s another way to do this without counting, so maybe it’s the distance is the number?

Consciously Competent: I know that the number represents that distance it is from zero, and the absolute value will always be the distance. I wonder what happens with negative numbers?

Unconsciously Competent: I know that the distance a number is away from zero is always positive, because distance is not negative. Therefore, regardless of if the number is positive or negative, the absolute value will always be positive.
