⧉ Thαt is :

✤ 1 :positive value ➙ +vє value [ |a| ➙ a ]

✤ 2 :negative value ➙ +vє value [ |-a| ➙ a ]

✤ 3 :variable term ➙ +vє variable [ |x| ➙± x ]

❐ if value in the value in variable is negative, then

• |x| = -x [ minus sign makes -ve value +ve ]

• |x| = x [ there's no need to change if value is already positive ]
