Absolute value

The absolute value of a real number is its size, and you write it as

|x|   or as   Abs (x)

 


Explanation

The modulus indicates how far a number is from zero. So there is no sign or direction.

 


Example 1

You can calculate | 2 − 7 | as | −5 | and its distance to 0 is 5. That's why you get

| 2 − 7 | × 2 = 10
