Part one: The essentials
  Take it slowly: more haste, less speed
  Never pick a calculator until you know why you do the calculation-what you intend to do with the result, how you plan to interpret it
  Always seek a reaction to the calculator's result by asking questions: what does this mean? what does it imply? is it surprised? is it good or bad
  One useful trick is to guess at the result before you start the calculation. Then when you do it, you can see whether you are surprised or not. If you are surprised, you have found something interesting to think about. Is your intuition just off, or is the answer sending you a message? Either way you benefit: you make progress with the case, or you train your business intuition

Part two: some useful devices
don't try to do the whole calculation at once, break it down
Never put down a number on paper without units
Write only simplest calculation on the case itself. keep it neat and record your units.  
Always understand the units in your result of calculation should be stated.

Part three: How to slow down and understand more
separate your calculation. give each a title, write it down.
As soon as you finish the calculation, write down a sentence to conclude the result
This will often stimulate further calculation

Part Four: Searching for meaning
Your ability to  interpret the result of calculation partly depends on your experience.
Another way to illustrate what you think about the result is up and down.
Be aware of average: always ask is the average typical
Another way to understand the number is to flip over
When searching for numerical meaning, make liberal use of visual sense.
