[Tex/LaTex] How to use Palatino font for text and what about maths

Question

I would like to use Zapf's Palatino font for the text in my document, which also includes a lot of maths. And I would like a good font for the maths. This is a snapshot of what I am doing.

\documentclass[10pt,letterpaper]{memoir}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{mathpple}
\usepackage{upgreek}
\usepackage{mathpazo}
\usepackage{lipsum}

\begin{document}

\chapter{Demo}

Some regular text. \lipsum[1]

Now for some maths.

\begin{displaymath}
P_{N-1 + m} = \frac{C}{N-{1} + m} \binom{N_{2} - N_{1}}{m}
        \alpha^{m}\beta^{(N_{2} - N_{1}) -m}
\end{displaymath}

The number 27 is the sum of the first 5 odd prime numbers: $27 = 1+3+5+7+11$

\end{document}

To me the text and math fonts seem a good fit but the text does not look like Palatino.

Answer 1

I suggest that you not load the mathpple, mathpazo, and upgreek packages and, instead, load the newpxtext and newpxmath packages.

\documentclass[10pt,letterpaper]{memoir}
\usepackage{amsmath,amssymb}
%\usepackage{mathpple}
%\usepackage{upgreek}
%\usepackage{mathpazo}
\usepackage{lipsum}
\usepackage{newpxtext,newpxmath}

\begin{document}

Some regular text. \lipsum[2]

Now for some maths.
\begin{displaymath}
P_{N-1 + m} = \frac{C}{N-{1} + m} \binom{N_{2} - N_{1}}{m}\,
        \alpha^{m}\beta^{(N_{2} - N_{1}) -m}
\end{displaymath}
The number 27 is the sum of the first 5 odd prime numbers: $27 = 1+3+5+7+11$.

$\alpha\beta\gamma\delta$ vs.\ $\upalpha\upbeta\upgamma\updelta$

\end{document}
