Is there a computer program were i can write down numbers in a row. Like in a spreadsheet. Then i can take the next row and set up a formula that then gets put into a row
Lets say i have ROW A and B then in C i want A divided by B or maybe ROW A x 1.5 or something like this?
Can you do this in LibreOffice?

The thing is i have analyse 1000s of numbers so its a pain in the ass to do it all myself. Even simple stuff like turning numbers into % etc
