do the math 

1: It's logical, especially without anyone else's opinions.
2: Figure it out yourself, especially without anyone else's wisdom.

NOTE: "Do The Math" to me is based on happenings that are correctly added up and bottom-lined.

Milk Math

When a person combines milk of one percentage with milk of another in order to create milk with a lower fat content.

"Dude, I hate the way 1% milk tastes but I'm watching my weight. So I did some milk math and mixed 1% and 2% to get 1 1/2%. It's not as good as 2% milk, but it's better than 1%."

Ex-Math 

The logical study and application of basic mathematical principles to deduce when your significant other was last with their ex-boyfriend or girlfriend.

While founded in the scientific theory, ex-math should not be considered for a major field of study as the process is often characterized by the absence of objective and rational thought.

Girlfriend: "I wondered after I left about the age you said you were when you were with XX so I put everything in a calendar. You said you were 24 so that was a couple of months before me? :-) sorry. I try not to be curious about stuff as that is typically not a good thing. But I wondered it and so I'm just...um..saying that I was curious."

Boyfriend: "Well if you're going to use ex-math, put it on a Chinese calendar. That way I haven't been with her since last year. Does that make you feel better?"

Bank Math 

A method of financial management that involves rounding any transaction up to the next dollar amount. Bank math prevents any overdrafting of bank accounts because the amount remaining in the account is always more than you believe it to be.

Let's see, the burger is $4.79, and the fries are $2.19. So quick Bank Math, that's like $8, and I have $15 in my account, so I should have $7 left for tonight.
