What is a double inequality?

A double inequality is an inequality where there are two signs, as opposed to one.

Ex: an inequality could be 3x < 15

A double inequality could be 3x < 15 < x + 20

If you'd want to solve that double inequality, you split it into to expressions:

3x < 15 and x + 20 > 15

Then just solve.

x < 5 and x > -5

-5 < x < 5

If the absolute value inequality is of the form where the absolute value of the difference between a variable (X) and some constant (a) is compared to another constant (b) eg |X - a| compared with b, then if the comparison is &lt; or &acirc;&permil;&curren;, the compound inequality is a double inequality of the form c &lt; X &lt; d (or &acirc;&permil;&curren;), and if the comparison is &gt; or &acirc;&permil;&yen;, the compound inequality is a disjoint inequality of the form X &lt; c or X &gt; d (or including the equals). In both cases, c = b - a, d = b + a (&gt;c)

No. An inequality must have an inequality sign, for example, "&lt;".
