What are the 5 types of inequality in maths?

The five inequality symbols in Maths are greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), and not equal to symbol (≠)

1. Greater than. x>y
2. less than. x<y
3. equal to. x=y
4. greater or equal to. x>=y
5. less or equal to. x<=y

1. Greater than (>)
2. Less than (<)
3. Greater than or equal to (≥)
4. Less than or equal to (≤)
5. Not equal to (≠)

 Not equal (≠), Strict Inequalities (>, <), and Slack Inequalities (≥, ≤).

Great than, Less than, Greater or equals, Less than or equals, not equals.

In mathematics, inequality refers to a comparison between two values or expressions, indicating that they are not equal. Here are five common types:

1. Strict Inequality (>) or (<): Indicates that one value is strictly greater than or less than another. Example: x>5x > 5, y<3y < 3.
2. Non-strict Inequality (≥) or (≤): Includes equality as a possibility. Example: x≥5x \geq 5, y≤3y \leq 3.
3. Linear Inequalities: Inequalities involving linear expressions, often seen in graphing and solving systems. Example: 3x+2>73x + 2 > 7.
4. Polynomial Inequalities: Involving polynomials, such as quadratic or higher degree equations. Example: x2−4x+3≤0x^2 - 4x + 3 \leq 0.
5. Absolute Value Inequalities: Involving the absolute value of expressions. Example: ∣x−3∣>2|x - 3| > 2, which translates to two inequalities: x−3>2x - 3 > 2 or x−3<−2x - 3 < -2.

Inequalities play a vital role in algebra, calculus, optimization, and other branches of mathematics.

2) <

3) ≤

4) ≥

5) ≠

The 5 that we use most are

1) Greater than

2) Less that

3) Equal to

4) Greater than or equal to

5) less than or equal to

There is also an identity (like an equals but with three lines instead of two). This is usually used in algebra - you can find this on a higher paper.

We can express inequalities as symbols or number lines or even be asked to solve an inequality.

The five inequality symbols in Maths are greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), and not equal to symbol (≠).

< means less than

≤ means less than or equal to

= means equal to

≥ means greater than or equal to

> means greater than

greater than or equal to >=, less than or equal to <=, greater than >, less than <, not equal to !=
