'''Math Operations'''

 Since you do NOT have to declare the data-type of a variable <br>(like in a compiled language such as "'''C'''"), numbers would be stored as '''text''' in variables. <br>Therefore, it is important to use the construct <span style="color:blue;font-family:courier;font-weight:bold">(( ))</span> surrounded by number, variables and math operations to convert numbers (stored as text) into '''numbers'''.
