Lorem Ipsum is simply dummy text of the printing and typesetting
industry. Lorem Ipsum has been the industry's standard dummy text ever
since the 1500s, when an unknown printer took a galley of type and
scrambled it to make a type specimen book. It has survived not only five
{\small\[
A / B + C = D
\]}
centuries, but also the leap into electronic typesetting, remaining
essentially unchanged. It was popularised in the 1960s with the release
of Letraset sheets containing Lorem Ipsum passages, and more recently
with desktop publishing software like Aldus PageMaker including versions
of Lorem Ipsum.

改善を提案してくれたTobiに感謝します。
\penalty\postdisplaypenalty（表示後の改ページを避けるために必要）などの詳細に踏み込む必要がなく、上と下のスキップを回避できるよりシンプルなアプローチ\normalsizeは、
\newsavebox{\vardisplaymathbox}
\newenvironment{vardisplaymath}[1][\small]
