It's mathematically proven... Also, girls are money squared. Click here if you want a demonstration of said evil~
Quite the interesting conclusion. However, I would like to suggest that the idea of girls requiring time and money will actually be written as the equation "Girls = Time + Money," leading to the conclusion of "Girls = 2×√Evil." Assuming money is the root of all evil, this means that girls are twice as valuable as money.

Hmph! I'm not like other girls. I don't require time or money! All I need is double the food! So, Shizu=FOOD^2 and... And I don't know what's next.
What if its a single girl? This equation only apply to Girls. Meaning that your most likely going to be fine on Earth but if you get isekai'd, then Houston we have a problem.
