Group your math in between [[ and ]].
• Exponents: Do [[x^{2}]] instead of x^2 to get $x^2$
• Polynomials: [[3z^{2}-5z+7]] for $3z^2-5z+7$
• Fractions: Use @frac for fractions as in [[@frac{2x}{3y+1}]] for $\frac{2x}{3y+1}$ or [[@frac{2}{3}]] for $\frac{2}{3}$
• Square roots: Use @sqrt as in [[@sqrt{155x}]] for $\sqrt{155x}$
• Symbols: @Delta for $\Delta$, @times for $\times$ @div for $\div$, @pm for $\pm$
• Greek: @pi for $\pi$, @alpha for $\alpha$, etc.
• Calculus: @int for $\int$, as in [[@int_0^{10} sin(x) dx]] for $\int_0^{10} sin(x)dx$.
• Subscripts: Use _ as in [[x_{0}]] for $x_0$
• Examples:
• You type: The slope of a line is [[m=@frac{@Delta y}{@Delta x]] to get The slope of a line is $m=\frac{\Delta y}{\Delta x}$.
• You type: I need help multiplying [[(x^2+5x+3)(2x-7)]] to get I need help simplifying $(x^2+5x+3)(2x-7)$.
• You type: Can someone help me add the fractions [[@frac{1}{3}+@frac{5}{17}]]? to get
Can someone help me add the fractions $\frac{1}{3}+\frac{5}{17}$?
• You type: Please show me how to simplify [[@sqrt{125}]] to get Please show me how to simplify $\sqrt{125}$.
• Yes it's LaTex. See these examples, but replace the blackslash with an @ symbol.
