What is "e"? What does e stand for, what equations can it be used in? And what fields use it, what applications does it have? Just wondering. i know I've heard of e, but I have no idea what it is used for.

Thanks for your thoughts!

Right now, we are having a huge storm with rain, thunder, and lightening, courtesy of Mother Nature! I was outside on my balcony watching the sky lighting up, but I got scared and came back in! The lightening is really close and goes right across the sky! There is continuous rumbling and loud cracks of thunder!

I'm not a wuss, but I have a friend who has been hit by lightening twice and suvived!

All you can hear outside is people with their ooohs and aaaahs!

Hey, I'm doing some algebra stuff, but I don't know how to do what I'm working on. Here's some examples of what I'm dealing with:

(2a - 3)/6 = (4a)/3 + 2/3

(3x)/5 + 3/4 = (6x)/10

(2b - 3)/7 - b/2 = (b + 3)/14

Could anyone tell me how to solve these problems and others like them?

I was told a leap year was every 4 years but now i've been told the year has to be divisible by 4 or 400 and then i was told it happened every 97 years and it's all very confusing. If anyone can just tell me when the next leap year happens and when they happen it would ease my troubled mind
