Answers to Questions

How to solve an inequality?

dCode can solve all inequalities and find variables.

Example: $ x+2 > 0 $ has for solution $ 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 (not in interval notation form).

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

What are allowed operators in an inequality?

Inequation operators alowed by the calculator are

- < (strictly inferior to, less than)

- <= (less than or equal to)

- > (strictly superior, greater than)

- >= (greater than or equal)

- <> (different, not equal)

How to solve an inequality step by step?

The calculating steps from the inequality solver are not displayed because the calculator is based on informatics operations that do not correspond to those of a hand-made resolution.
