I've gotten a few different answers. Can someone check my work to confirm the stack and calculation is correct?

Evaluate the postfix expressions by using the algorithm in the book. You MUST show the steps and the contents in the stack to get full credit.

Postfix expression: 2 4 / 6 8 - +

\begin{tabular}{|c|c|c|c|} \hline & & & \begin{tabular}{l} from the \\ stack (8 \\ and 6), \\ perform \\ the \\ subtraction \\ operation, \\ and push \\ the result \\ back onto \\ the stack \\ (68). \\ \end{tabular} \\ \hline \multirow[t]{2}{*}{7} & + & \begin{tabular}{l} 9 \\ \end{tabular} & \begin{tabular}{l} Read the token + \\ from the \\ input. Pop \\ the top \\ two \\ elements \\ from the \\ stack (68 \\ and 1.0), \\ perform \\ the \\ addition \\ operation, \\ and push \\ the result \\ back onto \\ the stack \\ (69.0). \end{tabular} \\ \hline & End of expression (Answer) & \begin{tabular}{l} 24/68+ is 69.0 . \\ Pop 69.0 \end{tabular} & \begin{tabular}{l} Pop 69.0 \\ 24/68+ is \\ 69.0. \end{tabular} \\ \hline \end{tabular}
