• Everthing following the \normalsize command will be output in the smallest predefined font size until the system encounters another font size command.
• \normalsize is the default font size, i.e. the size automatically chosen if there is no font size command
• Ex.: $$\normalsize~3x$$ gives $\normalsize~3x$

• inserts a double space of current character set size
• Ex.: $$a\qquad~b$$ gives $a\qquad~b$

• inserts a space of current character set size
• Ex.: $$a\quad~b$$ gives $a\quad~b$

• \small
• Ex.: $$\small~3x$$ gives $\small~3x$

• Everthing following the \tiny command will be output in the smallest predefined font size until the system encounters another font size command.
• Ex.: $$\tiny~3x$$ gives $\tiny~3x$

• Syntax: \left<...\right>
• Ex.: $$\left<f,g\right>$$ gives

$\left$

• Type arithmetic operations and "=" as usual.
• Exp.: $$f(x)=x-2b+(3a/c)$$ gives

$f(x)=x-2b+(3a/c)$

• See also keyword "fraction" for extended capabilities.

• Syntax for an n-dimensional array:
  \begin{array}a₁&...&a_n\end{array}
• Ex.: $$$\begin{array}a_{\fs{0}1}\fs{3},&a_{\fs{0}2}\fs{3},&a_{\fs{0}3}\end{array}$$$ gives

$(\begin{array}a_{\fs{0}1}\fs{3},&a_{\fs{0}2}\fs{3},&a_{\fs{0}3}\end{array})$
