Sum Column Calculations With $

Hello,

I'm trying to build a simple report that shows a list of certain accounts and a sum of their ARR. However, when I try to sum the ARR column, the report doesn't return anything. I suspect this is because the ARR includes a $, as I tested this same thing with other numbers that didn't include symbols and the summing worked properly then 

I can't remove the $ as it's coming straight from Salesforce. This seems like it should be easy to do. Is there something I'm missing?
