The answer will be either a suitable J sentence or blank if none can be found. This"J sentence" means that, for example, the sentence <code>8*7-4*1</code> is equivalent to the sentence <code>8*(7-(4*1))</code>. [Many infix languages use operator precedence to make polynomials easier to express without parenthesis, but J has other mechanisms for expressing polynomials and minimal operator precedence makes the language more regular.]
