The same font as latex for PowerPoint

The default font of LaTeX is Computer Modern which is only available as bitmap fonts. However, there are a few clones which resemble it very closely in OpenType format:

1. Latin Modern

2. Computer Modern Unicode

   Despite the name this does not provide the exact same shapes as the original Computer Modern.

In both cases, go to the download page and select the OTF files. Then follow Microsoft's instructions to add the fonts to your system: https://support.microsoft.com/en-us/office/add-a-font-b7c5f17c-4426-4b53-967f-455339c564c1

To change the math font, take a look at this post over at superuser.com: https://superuser.com/questions/1114697/select-a-different-math-font-in-microsoft-word

If you load usepackage{fontspec} and compile in LuaLaTeX or XeLaTeX, you can use any font in your LaTeX documents that you could use in Office, with setmainfont, setmonofont, etc.

If you load unicode-math, you can also use the same OpenType math fonts as in a MathML document or the Office equation editor, with setmathfont.
