Such errors are either obvious or invisible. A remedy is often to figure the 
problem on paper (or in your head if you're good at thinking visually). Here, 
just draw a line segment with secret in the middle and the interval borders 
around. Then, write there on the drawing the _values_ of the borders, as 
arithmetic expressions.
