Why the Negative? (Rules of Thumb):
1.
Notice that present value and future value are always opposite in sign.
2.
Use the "Inflow-Outflow" way of thinking:
Inflow is money "coming in the door" and outflow is money "going out".
3.
If all else fails, try changing the sign of any of the inputs to see how it affects the result and act accordingly.
4.
Don't get "burned" by the negative or lack of a negative. In other words, always keep it in the back of your mind.
Note: The formulas in the gray boxes above are cell-protected. The word 'byui' is the password if you wish to turn off the protection. Also, understanding
the role that the
negative
plays is crucial. You may want to scroll several rows down below to read more about it.
