The aim of this paper is to study the oscillation of the second order advanced neutraldifferentialequations%\begin{equation*}\left(r(t)\left[x(t)+p(t)x(\tau(t))\right]'\right)'+q(t)x(\sigma(t))=0. \tag{$E$}\end{equation*}%Obtained results are based on the new comparison theorems, thatenable us to reduce problem of the oscillation of the second orderequation to the the oscillation of the first order equations.Obtained comparison principles essentially simplify theexamination of the studied equations.
