title: How to get formula between parenthesis with regex?
body: <p>Normally, a formula with parenthesis, followed by a digit, has to be multiplied. For example:</p>
  
  <pre><code>(2* 4)(2*1-1)3 is equals to (2 *4)\*(2*1-1)*3
  </code></pre>
  
  <p>But i want to split a string after the parenthesis, i think with an regex. After that, i want to calculate it with mathjs as individual formulas.</p>
  
  <p>What i want:</p>
  
  <pre><code>(2* 4)(2*1-1)3 = 813
  </code></pre>
  
  <p>A complete string, including multiple parenthesis:</p>
  
  <pre><code>N 52 11. (1+(3+2 ) /2) (56* 7)( 2*1-1) 7 E 005 36. (1+7) 9 (6*1)
  </code></pre>
  
  <p>The regex i have now: <code>/\([0-9+\-\(* \/]+\)/g</code></p>
  
  <p>But that doesnt match the digits and gives a problem with double parenthesis.</p>
  
  <p>How can i accomplish this?</p>
