Getting started with deck.js:
simplemath extension
use right arrow to move on

“simplemath”: What?

• Add math equations in your slides
• Use latex syntax
• Just wrap your maths in a "span" element
• Wants to learn latex syntax?
• view the source of this page
• view online resources (there are a lot)
• … examples on the next slide

“simplemath” in action

• e=mc^2           (\frac{x^2}{y^3})           [\begin{array}{cc} \sqrt{x} & 2 \\ 3 & x^4 \end{array}]
• f(n) = \left\{ \begin{array}{l l} n/2 & \mbox{if } n \mbox{ is even}\\ -(n+1)/2 & \mbox{if } n \mbox{ is odd} \end{array}
• a^2 + \frac{1}{\sqrt{a^2 + \frac{1}{\sqrt{a^2 + \frac{1}{\sqrt{a^2 + b^{\infty}}}}}}}

Principle

• Written in Javascript
• Interprets latex syntax
• Generates MathML (web standard for maths)
• Lets your browser render the MathML


• Works fully offline
• − depends on browser support for MathML
• + works offline :)

Browser support

• Did it work for you? :)
• See the wikipedia page on MathML
