I use a number of conventions in my calculations that may be unfamiliar. Explanations follow:

• [] - Square brackets hold the same priority as normal brackets, but indicate that the value of the contents should be rounded down to the nearest whole number (integer) once calculated.
• rnd(x,y) - This is the expression of a random whole number (integer) between x and y. eg. rnd(3,50) would be a whole number (integer) between 3 and 50.
• min(x,y) - This expression indicates that you should take the lower of x and y.
• max(x,y) - This expression indicates that you should take the higher of x and y.
• x^y - This is x to the power of y. That is, x multiplied by itself y times. eg. 5^3 would be 5*5*5.
• {} - Curly brackets hold the highest priority, even higher than square and normal brackets. They indicate that the contents should be rounded down to the nearest whole number (integer) once calculated. Then, if the result is less than 0, it should be made equal to 0.
