In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. [1] It is used most often to compare two numbers on the number line by their size. The main types of inequality are less than (<) and greater than (>).

The meaning of inequality is to say that two things are NOT equal. One of the things may be less than, greater than, less than or equal to, or greater than or equal to the other things. 1. p ≠ q means that p is not equal to q 2. p < q means that p is less than q 3. p > q means that p is greater than q 4. p ≤ q means that p is less than or equal to ...
When inequalities are linked up you can jump over the middle inequality. 1. If, p < q and q < d, then p < d 2. If, p > q and q > d, then p > d Example: If Oggy is older than Mia and Mia is older than Cherry, then Oggy must be older than Cherry.
Swapping of numbers p and q results in: 1. If, p > q, then q < p 2. If, p < q, then q > p Example: Oggy is older than Mia, so Mia is younger than Oggy.
Adding the number d to both sides of inequality: If p < q, then p + d < q + d Example: Oggy has less money than Mia. If both Oggy and Mia get $5 more, then Oggy will still have less money than Mia. Likewise: 1. If p < q, then p − d < q − d 2. If p > q, then p + d > q + d, and 3. If p > q, then p − d > q − d So, the addition and subtraction of the s...
If you multiply numbers p and q by a positive number, there is no change in inequality. If you multiply both p and q by a negative number, the inequality swaps: p qd (inequality swaps) Positive case exam...
Putting minuses in front of p and q changes the direction of the inequality. 1. If p < q then −p > −q 2. If p > q, then −p < −q 3. It is the same as multiplying by (-1) and changes direction.
Taking the reciprocal1/value of both p and q changes the direction of the inequality. When p and q are both positive or both negative: 1. If, p < q, then 1/p > 1/q 2. If p > q, then 1/p < 1/q
A square of a number is always greater than or equal to zero p2 ≥ 0. Example: (4)2= 16, (−4)2 = 16, (0)2= 0
Taking a square rootwill not change the inequality. If p ≤ q, then √p ≤ √q (for p, q ≥ 0). Example: p=2, q=7 2 ≤ 7, then √2 ≤ √7 The rules of inequalitiesare summarized in the following table. Here are the steps for solving inequalities: 1. Step - 1: Write the inequality as an equation. 2. Step - 2: Solve the equation for one or more values. 3. Ste...
While writing the solution of an inequality in the interval notation, we have to keep the following things in mind. 1. If the endpoint is included (i.e., in case of ≤ or ≥) use the closed brackets '[' or ']' 2. If the endpoint is not included (i.e., in case of < or >), use the open brackets '(' or ')' 3. Use always open bracket at either ∞ or -∞. H...
A mathematical statement which makes a non-equal comparison between two mathematical expressions, and which can be further categorized into the following three types: Loose inequality: when the comparison symbol is $\le$ or $\ge$. Strict inequality: when the comparison symbol is $<$ or $>$. Inequation: when the comparison symbol is $\ne$.
In mathematics, inequality occurs when a non-equal comparison is made between two mathematical expressions or two numbers. In general, inequalities can be either numerical inequality or algebraic inequality or a combination of both.
In Mathematics, inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths.

- An example of a linear inequality is 3x-2y> 1. Here, the LHS of the inequality equation is strictly greater than RHS.
- If the inequality has variables on both sides, try to isolate the variable. In this process, flip the inequality sign whenever we divide or multipl...
- Both linear inequalities and linear equations are mathematical statements that relate two expressions to each other.
In mathematics, a relationship between two expressions or values that are not equal to each other is called ‘inequality.’. So, a lack of balance results in inequality. For example, if you want to buy a new bicycle that costs 250, b u t y o u h a v e 225. It is also an inequality as you are comparing two numbers that aren’t equal.
