For the less dev tools savvy, you could leave those top instructions on solving 2x - 3 = 4 in a console.log in your code. So once they get dev tools open they see some more instructions for the next step.

  console.log("Type the following in this order pressing enter each time you see a semi-colon: \n var expr = new Expression('x'); \n expr = expr.subtract(3); \n expr = expr.add('x'); \n console.log(expr.toString()); \n var eq = new Equation(expr, 4); \n console.log(eq.toString()); var x = eq.solveFor('x'); \n console.log('x = '' + x.toString());");

Very cool project by the way.

That's a very clever idea. Thanks.
