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

What does Inequality mean in math?
In mathematics, an inequality is a statement about the relative size or order of two values.
When a quantity is added to or subtracted from both sides of an inequality the resulting inequality will have the same direction as the original one?
When a quantity is subtracted or added from both sides of an inequality, the true difference in value is varied thereby changing the direction of the inequality, but when rather than subtracted or added it is multiplied or divided, it preserves the true difference in value thereby facing the same direction as the initial inequality.
What mean inequality?
Not the same as, or different from.
What is the inequality sign for at most?
Less than or equal to. :)
