==== Example 1 ====
  * A simple example
<acm>
   f(x)=sum_(n=0)^oo(f^((n))(a))/(n!)(x-a)^n
</acm>

==== Example 2 ====
Matrices and column vectors are simple to type
<acmath>
 [[a ,  b ],[c,  d]]((n),(k))
</acmath>

==== Example 3 ====
Grouping brackets don't have to match
<acmath>
(a,b]={x in RR | a < x <= b}
</acmath>

==== Example 4 ====
piecewise defined function are based on matrix notation
<acmath>
x/x={(1,if x!=0),(text{undefined},if x=0):}
</acmath>

==== Example 5 ====
Complex subscripts are bracketed, displayed under lim
<acmath>
d/dxf(x)=lim_(h->0)(f(x+h)-f(x))/h
</acmath>

==== Example 6 ====
  * A multi-lines formula
<acm> int (x+1)(e^(x//2) - 1) dx = (x+1)(2e^(x//2) - x)- int (2e^(x//2)-x) dx</acm>

<acm> \ \ \ \ =(x+1)(2e^(x//2) - x) - (4e^(x//2) - x^2/2) + C</acm>

<acm> \ \ \ \ = 2xe^(x//2) -x^2 + 2e^(x//2) -x - 4e^(x//2) + x^2/2 + C</acm>

<acm> \ \ \ \ = 2e^(x//2)(x-1)-x-x^2/2 + C</acm>



==== Example 7 ====
  * Prescripts simulated by subsuperscripts
<acmath>
{::}_(\ 92)^238U
</acmath>


  * Symbols can be stacked
<acmath>
 stackrel"def"= or \stackrel{\Delta}{=}" "("or ":=)
</acmath>


  * Accents can be used on any expression 
<acmath>
 hat(ab) bar(xy) ulA vec v dotx ddot y
</acmath>
