<h1>About</h1>
<div>This class basically can be used to perform the following operations on matrices:</div>
<ol>
<li>Find the transpose of a matrix</li>
<li>Multiply two compatible matrices</li>
<li>Multiply a matrice by a scalar</li>
<li>Add matrices</li>
<li>Subtract matrices</li>
<li>Find the:
<ul>
<li>determinant of any square matrix</li>
<li>inverse of a 2x2 matrix</li>
<li>minor matrix of a 2x2 matrix</li>
<li>cofactor matrix of a 2x2 matrix</li>
<li>adjoint matrix of a 2x2 matrix</li>
</ul>
<li>Literally, divide 2x2 matrices by multiplying the divided by the inverse of the divisor.</li>
</ol>
</div>
