Step by step math solutions

// Evaluates a node to a numerical value
// e.g. the tree representing (2 + 2) * 5 would be evaluated to the number 20
// it's important that `node` does not contain any symbol nodes

function evaluate(node) {
  // TODO: once we swap in math-parser, call its evaluate function instead
  return node.eval();
}
