How the Inequality Solver Works?
An inequality is a mathematical expression indicating that one quantity is greater, less, or equal to another, often using symbols like <, >, ≤, or ≥. The inequality solver identifies the type of inequality, applies algebraic rules, and computes solutions automatically. It handles linear, quadratic, and higher-order inequalities efficiently.
How the Calculator Solves Inequalities?
The online calculator follows a systematic approach:
- Identifies variables, coefficients, and inequality signs
- Applies arithmetic or algebraic operations to isolate the variable
- Handles multiplication/division by negative numbers correctly
- Solves linear, quadratic, or polynomial inequalities
- Provides step-by-step solutions and visual representations when needed
Why Inequalities Matter?
Inequalities are widely used in mathematics, economics, physics, and engineering to represent constraints, optimize solutions, and analyze real-world situations. Understanding their solutions helps in decision-making, problem-solving, and modeling scenarios accurately. Using an inequality solver ensures correctness and saves valuable time. It is one of many essential tools you can find in our main Maths Calculators hub.

Examples of Using the Inequality Solver
Try these examples to understand how the calculator works:
- 2x + 5 < 11 → x < 3
- x² - 4x + 3 ≥ 0 → x ≤ 1 or x ≥ 3
- 3x - 7 > 2x + 1 → x > 8
- 4x² + x - 3 ≤ 0 → -1 ≤ x ≤ 0.75
- (x - 2)(x + 5) > 0 → x < -5 or x > 2
These examples illustrate how effortlessly you can solve inequalities with accurate solutions and visual understanding.
