Equation Solver Pro

Equation Solver Pro helps you solve supported equations and inequalities and review the solution steps. Enter a problem to see an answer and an explanation. You can copy the answer, copy the steps, or share the result as text or an image.
Supported problem types
•Polynomial equations up to degree four, with real solutions
•Polynomial inequalities up to degree four
•Absolute-value equations and inequalities with a linear expression inside the absolute-value bars
•Basic rational inequalities in the form of a quotient of linear expressions compared with a constant
•Exponential equations in the supported form, such as 2^x = 8
•Logarithmic equations in the supported form, such as log(2, x) = 3
•Systems of two or three linear equations
Calculation history and settings Calculations are saved locally on your device. The app keeps up to 50 recent non-favorite calculations; favorites are stored separately. You can search your history, reopen or copy a calculation, remove individual entries, clear non-favorites, or delete all history and favorites. Settings include dark, light, and system themes, and a choice between detailed solution steps and a shorter explanation.
Limitations Only the problem types and formats listed above are supported. Polynomial answers show real solutions; results may be rounded. Some higher-degree solutions are found numerically. Please check results independently when precision is important.
