Ka-ching!
In the interests, therefore, of furthering the march of civilization, I propose the following innovations in symbology that we could use to express difficult mathematical concepts in our everyday life.
Moneygon: The difference between how much you think something should cost and how much it actually does.
Timesuk: Similar to the Moneygon, this represents the difference between the time you anticipated for a project, and the actual time required.
Bytestop: The number of times you can chew your food at dinner before a telemarketer calls.
Infinitube: The function of infinitely reducible quantity of dentifrice. That is, no matter how much toothpaste you get out of the tube, there's still enough left to brush your teeth one more time.
Fumego: How many additional miles you can go after your fuel light comes on.
