\begin{definition}[Definition:Leibniz Harmonic Triangle/Row]
Consider the Leibniz harmonic triangle:
{{:Definition:Leibniz Harmonic Triangle}}
Each of the horizontal lines of numbers corresponding to a given $n$ is known as the '''$n$th row''' of Leibniz harmonic triangle.
Hence the top '''row''', containing a single $1$, is identified as the '''zeroth row''', or '''row $0$'''.
