We can think of the absolute value of a number as its distance from 0. So, the absolute value of a, which is denoted by is always greater than 0. In this post, we are going to prove that for all real numbers a, |-a| = |a|. There are two possible cases: and $latex b […]

## Absolute Value Proofs: Products and Quotients

The absolute value of a number is its distance from 0. Thus, all absolute values are either positive or 0. That is, if we have a number , then the absolute value of which can be written as is equal to (a) if is positive (b) if is negative (c) if is 0. Also, for […]
