Math Column

Hi all,

I have a math column with formula. Its called Final Price.
I used the action to add row in Google Sheet.
I noticed, the column in Google Sheet - Final Price is the number with apostrophe.
When I used the data in Google sheet to do some analysis, its showing the sum of 0.
My question is how to add row but without the apostrophe?

You should be able to format it in the Google Sheet.

What does apostrophe mean?
