有限数学示例

[\begin{matrix} - 3 & 8 & 4 \end{matrix}] - [\begin{matrix} 4 & 3 \end{matrix}]

$[\begin{array}{c} - 3 & 8 & 4 \end{array}] - [\begin{array}{c} 4 & 3 \end{array}]$

解题步骤 1

[\begin{matrix} - 3 & 8 & 4 \end{matrix}] - [\begin{matrix} 4 & 3 \end{matrix}]

$[\begin{array}{c} - 3 & 8 & 4 \end{array}] - [\begin{array}{c} 4 & 3 \end{array}]$
