This article lists a few sample LaTex equations for use in our math editor.

Multi-line equations

- To align, you should use the
**Blockmath**option, by clicking the appropriate radio button below the text entry window in the equation editor. - The location of the
**&**symbol indicates the point of horizontal alignment. - Lines
be ended with*must***\\**. - The ‘\’, ‘\quad\’, and ‘\qquad’ commands force 1, 4, and 8 blank spaces, respectively.

**Example 1:**

*Latex Code:*

\begin{align}

&= 2-144 \times 62 && \text{Multiply:} \ 144 \times 62 = 8928\\

&= 2 - 8928 && \text{Subtract: 8928}\\

&= - 8926

\end{align}

**Example 2:**

*Latex Code:*

\begin{align}

&= 2-144 \times 62 \\

&= 2 - 8928 \\

&= - 8926

\end{align}
