What formula should I use to change a cell value with - and + signs

Hello all,

I would like to change my cell value, which contains a minus (-) or a plus (+) in it, to a cell with Inflow (for the + signs) and an outflow (for the minus signs). So the Inflow cell should check if the value in column A is plus or minus and insert it into the Inflow or Outflow without the symbols, so I can calculate with the currencies. I have attached my spreadsheet for clarity.

Thanks!
