Easiest way to add in excel?

Hi all, i have a huge table with rows and i am trying to add 0,95 to each. So far i am adding 0,95 into each cell and it is painstakingly slow. Is there a faster way of doing this? I was thinking of adding 0,95 to row i.e C + 0,95, D + 0,95 etc but that does not make sense.

Thanks for the help

Thanks for that
