I have two tables. One shows when to multiply by PV, A, etc. the other doesnt.

How do I know when to if I use the table that doesnt show the exact formula?

\begin{tabular}{|l|c|c|c|} \hline \multicolumn{1}{|c|}{ Factor Name } & Converts & Symbol & Formula \\ \hline SinglePaymentCompoundAmount & to F given P & (F/P,i%,n) & (1+i)n \\ \hline SinglePaymentPresentWorth & to P given F & (A/F,i%,n) & (1+i)n1i \\ \hline UniformSeriesSinkingFund & to A given F & (A/P,i%,n) & (1+i)n1i(1+i)n \\ \hline CapitalRecoverytoAgivenP & to F given A & (F/A,i%,n) & i(1+i)n1 \\ \hline UniformSeriesCompoundAmount & to P given A & (P/A,i%,n) & i(1+i)n(1+i)n1 \\ \hline UniformSeriesPresentWorth & to P given G & (P/G,i%,n) & i2(1+i)n(1+i)n1i(1+i)nn \\ \hline UniformGradientPresentWorth & to F given G & (F/G,i%,n) & i2(1+i)n1in \\ \hline UniformGradientFutureWorth & to A given G & (A/G,i%,n) & i1(1+i)n1n \\ \hline UniformGradientUniformSeries & & & (A/F) \\ \hline \end{tabular} \begin{tabular}{|l|c|c|} \hline Conversion & Formula & Factor Value \\ \hline Present Value to Future Value & FV=PVx(1+i)n & Multiply PV by (F/P, i, n) \\ \hline Future Value to Present Value & PV=(1+i)nFV & Multiply FV by (P/F, i, n) \\ \hline Present Value to Annual Value & A=PV((1+i)n1i(1+i)n) & Multiply PV by (A/P, i, n) \\ \hline Annual Value to Present Value & PV=A(i1(1+i)n) & Multiply A by (P/A, i, n) \\ \hline Annual Value to Future Value & FV=A(i(1+i)n1) & Multiply A by (F/A, i, n) \\ \hline Future Value to Annual Value & A=FV((1+i)n1i) & Multiply FV by (A/F, i, n) \\ & & \\ \hline \end{tabular}
