Mathsteps

Mathsteps is a step-by-step math solver. It helps in solving equations, simplifying an expression and factoring a polynomial. (more to come 😄)

Solve an equation

const steps = mathsteps.solveEquation('2x + 3x = 35');

See all the change types

const changes = mathsteps.ChangeTypes;

Learn how to use mathsteps and how the codebase works.

Examples

Here is an example to get you started.

const mathsteps = require('mathsteps');
 
const steps = mathsteps.simplifyExpression('2x + 2x + x + x');
 
steps.forEach(step => {
    console.log("before change: " + step.oldNode);        
    console.log("change: " + step.changeType);             
    console.log("after change: " + step.newNode);          
    console.log("no of substeps: " + step.substeps.length); 
});
 
/* 
before change: 2 x + 2 x + x + x
change: ADD_POLYNOMIAL_TERMS
after change: 6 x
no of substeps: 3
*/

In this example we have an equation 2x + 2x + x + x that is being simplified by the method simplifyExpression. It returns the output which tells about the equation before and after applying the change, what change was applied and the no of substeps.

Installation

Mathsteps is available as the mathsteps package on npm.
