Pronunciation of a Summation

[Stratosphere]

How would you say this in words?

[HallsofIvy]

"The sum, as n ranges from 1 to 24, of 2n-1".

[daviddoria]

I just see "attachments pending approval", but from what hallsoflvy said, I think you could also say

"the sum from n equals 1 to 24 of 2n-1"
or
"the sum of 2n-1 from n=1 to 24"

or since n is the only variable:
"the sum of 2n-1 from 1 to 24"
"the sum from 1 to 24 of 2n-1"

[Feldoh]

Wouldn't get too caught up in the notation as long as you know what it means, then you're fine.

[CRGreathouse]

"the sum from 1 to 24 of 2n-1"

Right, this is probably what I'd say since there's just one variable.
