Alright. I don't usually do this, but here I go. I have to do a chemistry worksheet over the weekend, and it's on significant digits and whatnot. This is part of it:

F. Evaluate the following answers expressed to the proper number of significant digits.

4.22E^5 + 3.11E^7 + 6.003E^6

Now, what does "E" mean? Ty

E=mc2


...duh!

E means the numbers before it are multiplied by 10.

edit: I think

So basically, the 4.22E^6 would be 4.22 x 10^6?

As for the color, what are you talking about? This is easy to read on both skins Maybe my monitor is too bright.

Yes, I think so.

Why not just put 4.22^5 then

I was leaning toward the E^6 meaning 10^6, but I'll wait for some more replies.

The E is the numbers before multiplied by 10. Scientific notation, beeyotches.

not quite... think of it literally as an expression.

3.5E6 = 3.5 x 10^6, right?

now use order of operations:

(3.5)(10^6) = (3.5)(10,000,000) = 35,000,000

so its more like the numbers before are multiplied by 10^x, mmmkay?
Maybe you knew this but im just trying to make it painfully clear.
