Greatest practical use of maths & why?
OK - What do you think is the greatest practical use for maths at the moment and why.
I think that members ought to be entitled to state whatever they like without fear of ridicule, AS LONG AS IT COMES WITH AN EXPLANATION - the piece of Maths in question could be broad or narrow, simple or advanced
I myself am not too sure, hence the question, but I would like to think that the following should be contenders:
use of enormous prime numbers in cryptography could be a contender, since upon it lies the whole enormous banking system used the world over and
The number zero, without which place value would not be possible

Using mathematics to find out how we are here, and why the universe came into existence is the greatest practical use of mathematics.

I like it.The computer I'm using is a massive calculator!

Figuring how much change your meant to get before the cashier does so you don't get shortchanged.
Or just simple maths we use everyday .... we'd be screwed without it. Hence why it is the greatest and most used

OK - but what about the mathematics that led to the discovery of quantum tunneling, the seemingly impossible magic trick that happens millions of times every second in every computing device in the world, including the computer that you are using
using area = pi*r^2 to work out which deals are the best value at pizza hut

To be fair, most things seem impossible until you discover an explanation.

That doesn't account for thickness or topping.

Yes it does! let z= radius a= thickness, volume = pi . z . z . a

I see that pun
Pos rep.
I guess I can go fairly specific - in my opinion the best use of maths (so far) was in forming Maxwell's Equations (below), which describe everything to do with electromagnetism. Everything.
EDIT: Also, the wave equation:

Taylor series.
The basis of how calculators use sin/cos etc functions. Without it calculators won't calculate important functions and then the whole world will end
