Removing a character throughout a column

[Sfinally]

I have a column of SKUs that have been broken up in one system by hyphens, but are uninterrupted numbers in another. I want to remove the dashes throughout the column so that they match the second system. Is there a simple way to do this?

Column A
12-455
11-555
43-908

Should read:

12455
11555
43908
