Hello, experts!

I'm here to ask you about the usage of 'difference between...'

Can you read the following and tell me which one is correct?


1) The difference in air pressure at the front and at the back

2) The difference in air pressure between at the front and at the back

3) The difference in air pressure between the front and the back


Please help~ Thank you for your time and attention.

hohokCan you read the following and tell me which one is correct?

Al three get the point across. Number 3 is the most likely, and 2 is the least likely. Oddly, number 1 doesn't even say what you mean, speaking as it does of two different air pressure differences, but people will know what you mean, anyway. Number 2 is still the least likely because it is wordy. Number 3 is the plain English of it.

Thank you for your precious time and comment, Expert Anonymous!

Those three bothered me all afternoon today and you finally saved me.

Thanks a lot.

Now I know which one I should use instead of others.

I learn something new everyday as usual. I wish you good luck, kind expert.

Have a good day and a good night ^^
