+* Écrire des Maths
+
+Equations can be formatted *inline* or as *displayed formulas*.  In the
+latter case, they are centered and set off from the main text.  In the
+former case, the mathematical material occurs smoothly in the line of
+text.
+
+In order to fit neatly in a line, summation expressions (and similar
+constructs) are formatted slightly differently in their inline and
+display versions.
+
+Inline mathematical material is set off by the use of single
+dollar-sign characters. Consequently, if you wish to use a dollar sign
+(for example, to indicate currency), you need to preface it with a
+back-slash.  The following examples, followed by their typeset
+versions, should make this clear
+
+#+BEGIN_EXAMPLE
+This summation expression $\sum_{i=1}^n X_i$ appears inline.
+#+END_EXAMPLE
+
+This summation expression $\sum_{i=1}^n X_i$ appears inline.
+
+#+BEGIN_EXAMPLE
+This summation expression is in display form.
+
+$$\sum_{i=1}^n X_i$$
+#+END_EXAMPLE
+This summation expression is in display form.
+
+$$\sum_{i=1}^n X_i$$
