## Mathematics

Jekyll uses MathJax, which the Electric Book workflow supports.

LaTeX-style maths via MathJax can be inline ($$E = mc^2$$) or displayed:

$P_{t+1} - P_t=\frac{b+d}{s}(P_t-\overline{P})$

The maths above and below is borrowed and adapted from The Economy by CORE.

$P_{t+2} - P_{t+1}=\frac{b+d}{s}(P_{t+1}-\overline{P})$

It follows from $$P_{t} = \overset{\overline{}}{P} - \frac{s}{b + d}E_{t}$$ , $$E_{t} = P_{t + 1} - P_{t}$$ and the equation above that

\begin{align} \frac{P_{t+2} - P_{t+1}}{P_{t+1} - P_{t}} &= \\ \frac{P_{t+1}-\overline{P}}{ P_{t}-\overline{P}} &= R \end{align}
