title: Sum, Subtract and Multiply arrays
body: <p>I've got the following arrays:</p>
  
  <pre class="lang-cs prettyprint-override"><code>int[,] myArray1 = new int[2, 3] { { 1, 2, 3 }, { 4, 6, 8 } };
  int[,] myArray2 = new int[2, 3] { { 6, 4, 3 }, { 8, 2, 8 } };
  </code></pre>
  
  <p>What I'd like to know how to do is:</p>
  
  <ol>
  <li><strong>Create a new array with the sum of myArray1 and myArray2</strong></li>
  <li><strong>Create a new array with the subtraction of myArray1 and myArray2</strong></li>
  <li><strong>Create a new array with the multiplication of myArray1 and myArray2</strong></li>
  </ol>
  
  <p>Result of sum would be:</p>
  
  <pre class="lang-cs prettyprint-override"><code>int[,] myArray3 = new int[2, 3] { { 7, 6, 0 }, { -4, 4, 0 } };
  </code></pre>
  
  <p>Result of subtraction would be:</p>
  
  <pre class="lang-cs prettyprint-override"><code>int[,] myArray3 = new int[2, 3] { { 5, 2, 6 }, { 12, 8, 16 } };
  </code></pre>
  
  <p>Result of multiplication would be:</p>
  
  <pre class="lang-cs prettyprint-override"><code>int[,] myArray3 = new int[2, 3] { { 6, 8, 9 }, { 32, 12, 64 } };
  </code></pre>
  
  <p>Can this be done similar to printing out the arrays, with for loops? I tried looking for examples but found none that I could use for my specific problem.</p>
