 The root-mean-square, average and most probable speeds of gas molecules are
 derived from the Maxwell-Boltzmann distribution. The Maxwell-Boltzmann
 distribution is a probability distribution that describes the distribution of
 speeds of particles in an ideal gas.
 
-The distribution is given by the following equation:
-    f(v) = (M/2πRT)^(3/2) * 4πv^2 * e^(-Mv^2/2RT)
+The distribution is given by the following equation::
 
-    .. math:: f(v) = \left(\frac{M}{2 \pi RT}\right)^{\frac{3}{2}} \cdot 4 \pi v^2
-                     \cdot e^{-\frac{Mv^2}{2RT}}

+        | f(v) = (M/2πRT)^(3/2) * 4πv^2 * e^(-Mv^2/2RT) |
+        -------------------------------------------------
 
 where:
-    * :math:`f(v)` is the fraction of molecules with a speed :math:`v`
-    * :math:`M` is the molar mass of the gas in kg/mol
-    * :math:`R` is the gas constant
-    * :math:`T` is the absolute temperature
+    * ``f(v)`` is the fraction of molecules with a speed ``v``
+    * ``M`` is the molar mass of the gas in kg/mol
+    * ``R`` is the gas constant
+    * ``T`` is the absolute temperature

 The average speed can be calculated by integrating the Maxwell-Boltzmann distribution
-from 0 to infinity and dividing by the total number of molecules. The result is:
+from 0 to infinity and dividing by the total number of molecules. The result is::
 
-    .. math:: v_{avg} = \sqrt{\frac{8RT}{\pi M}}
+        ---------------------
+        | v_avg = √(8RT/πM)  |

 The most probable speed is the speed at which the Maxwell-Boltzmann distribution
 is at its maximum. This can be found by differentiating the Maxwell-Boltzmann
-distribution with respect to :math:`v` and setting the result equal to zero.

+        ---------------------
+        | v_mp = √(2RT/M)    |

 The root-mean-square speed is another measure of the average speed
 of the molecules in a gas. It is calculated by taking the square root
-of the average of the squares of the speeds of the molecules. The result is:
