Doing the math in my head  
Making the numbers work  
Going through the motions  
Calculating the equation  
Computing the data  
Jotting down all the info  
Feeling I can get the answer  
Working out the kinks  
Getting closer to the solution  
Being near the end result  
Believing I have the answer  
Thinking it will all work out  
But the whole thing breaks down to  
Me divided by zero
