Q1
A student multiplies $135\times 24$ and writes this work:
$$
\begin{array}{r}
\ \ 135\ \times\ 24\ \hline
\ \ 540\ \ \ 270\ \hline
\ \ 810\ \end{array}
$$
Multiplication relies on place value, and partial products must represent multiplying by ones and tens correctly. Which statement best describes the error?
