In mathematics, |q| represents the absolute value of the variable q. The absolute value is the distance of a number from zero on the number line, regardless of its sign.
In mathematics, |q| represents the absolute value of the variable q.
The absolute value of a number is its distance from zero on the number line, regardless of its positive or negative sign.
For example, if q = -3, then |q| = 3. If q = 5, then |q| = 5.
The absolute value always makes the number positive.
So, when you see |q| in a math equation or expression, you know that it represents the positive value of q.
