Math Solver

PHP package to simplify mathematical expressions and solve equations.

Example

use MathSolver\Math;

Math::from('3x^2 + 2x * 4x')->simplify()->string(); // 11x^2

Math::from('2x + 3')->substitute(['x' => 5])->simplify()->string(); // 13

Installation

Usage

First, load an expression with the from method.

use MathSolver\Math;

Math::from('2x + 3x');

Then, you can chain one of these methods:

Simplify

Simplify the expression.

use MathSolver\Math;

Math::from('2x + 3x')->simplify()->string(); // 5x

Substitute values

Substitute a value into the expression.

use MathSolver\Math;

Math::from('2x + 3x')->substitute(['x' => 4])->string(); // 2(4) + 3(4)

The substitute methods pairs nicely with the simplify method.

use MathSolver\Math;

Math::from('2x + 3x')->substitute(['x' => 4])->simplify()->string(); // 20

Configuration

You can call the config method for any configuration options.

use MathSolver\Math;

Math::from('2x + 3 = 11')->config(['mathjax' => true, 'steps' => false])->...

These are all available options in short:

Name	Type	Default	Description
mathjax	bool	false	Whether to return Mathjax output
steps	bool	false	Whether to record and return steps

Mathjax

Mathjax is a tool to display mathematical expressions in your browser. Set this option to true so Math Solver will return responses in Mathjax syntax instead of the default one.

use MathSolver\Math;

Math::from('sqrt[18]')->config(['mathjax' => true])->simplify()->string(); // 3\sqrt{2}

Steps

Settings this value to true will Math Solver make record every step.

use MathSolver\Math;

Math::from('sqrt[18] + sqrt[32]')->config(['steps' => true])->simplify()->string();

// [
//     'result' => '7sqrt[2]',
//     'steps' => [
//         ['type' => 'simplify', 'name' => 'Simplify roots', 'result' => '3sqrt[2]+4sqrt[2]'],
//         ['type' => 'simplify', 'name' => 'Add like terms', 'result' => '7sqrt[2]']
//     ]
// ]

Mathematical syntax

Here are some functions that require another input syntax than you may be used to:

• Powers: five to the power of three is 5^3
• Roots: the cube root of 15 is cbrt[15]
• Fractions: two-thirds is frac[2, 3]
