This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • If you can't find your font in document's meta-data, you can compare your guess with fonts listed in The LaTeX font catalogue. – ebosi May 25 '17 at 19:18
  • @TeXnician No it's not a duplicate! I am asking for the math font, not the text font. – Heinz Doofenschmirtz May 25 '17 at 19:21
  • Where's the difference? If you have a PDF or something similar open the font information dialog. – TeXnician May 25 '17 at 19:22
  • @TeXnician will that give me the font they used in TEX for the MATH? – Heinz Doofenschmirtz May 25 '17 at 19:23

    @TeXnician: I'm pretty sure it's not a TeX output. Note the smaller font in fractions and strange kerns around - in superscripts. – Sergei Golovan May 25 '17 at 19:30

It looks like Century Schoolbook (or some other Schoolbook). For XeLaTeX or LuaLaTeX one could use TeX Gyre Schola Math which is pretty similar:

\documentclass[a4paper,12pt]{article}

\usepackage{amsmath}
\usepackage{fontspec}
\setmainfont{Century Schoolbook}
\usepackage{unicode-math}
\setmathfont{TeX Gyre Schola Math}
\usepackage[russian]{babel}

\newcommand{\efrac}[2]{\hbox{\footnotesize$\dfrac{#1}{#2}$}}

\begin{document}
Решите неравенство $\efrac{1}{x^2-15x+56}+\efrac{1}{x^2-19x+88}\leqslant0$.
\end{document}

enter image description here

The \efrac tries to imitate the Russian typographic tradition to use eight point font for display math fractions (it looks like that in your example).

  • Thank you so much! I finally found the font :) I am currently doing a research about Russian maths exams, could you elaborate on the typographic tradition? – Heinz Doofenschmirtz May 25 '17 at 19:39
  • I can't say much on traditions. I prefer to just use what LaTeX offers. This article lists some of them. – Sergei Golovan May 25 '17 at 19:45
