  • Handwritten determinant calculation on paper, rotated sideways, with matrices of binomial coefficients written as C with superscripts and subscripts, row and column operations, and the case note l = m_2 - (n-1) and k = m_2 at the bottom.

  • Handwritten working on lined paper: a series of determinant equalities with matrices of binomial coefficients C(n, k) and a bracketed note reading (l = m_k - (n-1)), ending with k = m_k and a note asking for next steps.
