Usage

To install mathsteps using npm:

npm install mathsteps

const mathsteps = require('mathsteps');

const steps = mathsteps.simplifyExpression('2x + 2x + x + x');

steps.forEach(step => {
	console.log("before change: " + step.oldNode);         // before change: 2 x + 2 x + x + x
	console.log("change: " + step.changeType);             // change: ADD_POLYNOMIAL_TERMS
	console.log("after change: " + step.newNode);          // after change: 6 x
	console.log("# of substeps: " + step.substeps.length); // # of substeps: 3
});

To solve an equation:

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

To see all the change types:

const changes = mathsteps.ChangeTypes;
