What are the properties of absolute value?
Absolute value has the following fundamental properties:
- Non-negativity |a| ≥ 0.
- Positive-definiteness |a| = 0a = 0.
- Multiplicativity |ab| = |a| |b|
- Subadditivity |a + b| ≤ |a| + |b|
- Idempotence ||a|| = |a|
- Symmetry |−a| = |a|
- Identity of indiscernible |a − b| = 0 ⇔ a = b.
- Triangle inequality |a − b| ≤ |a − c| + |c − b|
Why do we use absolute value?

How do you put absolute value in Excel?
The ABS function in Excel returns the absolute value of a number. In other words: the ABS function removes the minus sign (-) from a negative number, making it positive. 1. For example, the ABS function in cell B1 below returns the absolute value of a negative number.
What is an absolute formula in Excel?
An absolute reference in Excel refers to a reference that is “locked” so that rows and columns won’t change when copied. Unlike a relative reference, an absolute reference refers to an actual fixed location on a worksheet. To create an absolute reference in Excel, add a dollar sign before the row and column.
