HOW TO WRITE MATH-ORIENTED PROBLEMS (using the LOL software)
You make up the text for the question (graphics can be included):("m" & "a" are variables)
 
A hunter is _m meters away from a deer when he releases an arrow that 
moves at _a meters per second.  The sound of the shot also heads outward 
at 340 m/s.  How much time does the deer have in which to duck between when he hears the 
the arrow and when it reaches him? 

You write the program for the math to be performed:
 
a=r(100,175,1); 
m=r(60,100,1); 
scale=2; 
result= (m/a)-(m/340)%3;
 (the "r" tells the software to pick a randon number.  Here, it falls from 100 to 175,  in increments of one)
 ("scale=2" describes how many decimal places to carry out operations)
(in the last line is  the math done, followed by the % acceptable error)

You make up a hint, if you choose:
 
The "ducking time" starts when the deer hears the sound and ends when the arrow arrives.
You will need to find 2 times and do some subtraction. 


You may also give a description of the work done that is shown once the student gets the problem right.
