<p><b>Новая страница</b></p><div>== Advanced mathematical operations are provided through the Math object.==<br />
<br />
<p>The Math object is a built-in object containing properties and methods used for mathematical computation.</p><br />
<p>It is a predefined JavaScript object and can be accessed without the use of a constructor or calling method.</p><br />
<p>All Math properties and methods are static.</p><br />
