How do you write such expression? Very simple: using double dollar signs $$a^2 + b^2 = c^2$$ To display inline math use $…$ like this $sin(x^2)$ which gets rendered as … Here’s another example using type \mathsf $$\mathsf{Data = PCs} \times \mathsf{Loadings}$$ which gets displayed as… Or even better: $\mathbf{X} = \mathbf{Z} \mathbf{P^\mathsf{T}}$ is displayed as.. If you want to use subscripts like this Xn,p you need to scape the underscores with a backslash like so \mathbf{X}_{n,p}: $$\mathbf{X}_{n,p} = \mathbf{A}_{n,k} \mathbf{B}_{k,p}$$ will be displayed as…

Thanks to Jekyll, which is easy to make my blog here.
