Tool to solve inequalities. An inequation is a mathematical expression presented as an inequality between two elements with unknown variables.

Answers to Questions

How to solve an inequality?

dCode can solve all inequalities and find variables.

Example: \( x+2 > 0 \) gives \( x > -2 \)

Inequalities can be combined, either by writing one inequality per line, either with the and (logical conjunction) operator: && or ⋀.

Example: \( 2x+1 >= 0 \ \&\& \ 3x-1 >= 0 \)

Solutions are presented with logical simplifications (no interval notation form).

Be sure to correctly indicate the solving domain set, if the expected result is an integer, indicate the natural integers set N otherwise prefer the real numbers domain R. Use the complex domain C only if the solution is a complex number.

What are allowed operators in an inequality?

Operators < or <= for less (or equal), > or >= for greater (or equal), and <> for different.
