"One way is with a Polynomial class. For example,\r\n\r\n* `Poly:add(this, that)` returns the result of `this + that`.\r\n* `Poly:sub(this, that)` returns the result of `this - that`.\r\n* `Poly:mul(this, that)` returns the result of `this * that`.\r\n* `Poly:evaluate(this, evalmap)` returns the polynomial after replacing all free variables with constants as specified by `evalmap`.\r\n* `Poly:toList(this)` returns the polynomial in the correct output format.\r\n\r\n* `Solution::combine(left, right, symbol)` returns the result of applying the binary operator represented by `symbol` to `left` and `right`.\r\n* `Solution::make(expr)` makes a new `Poly` represented by either the constant or free variable specified by `expr`.\r\n* `Solution::parse(expr)` parses an expression into a new `Poly`."
