Making cells with a 0.00 just stay blank?

I have a spreadsheet in which there are several columns and rows in which 0.00 is the answer to a math equation. When the answer is 0.00, is there a way for the cell to simply remain blank? The cast array of 0.00s sometimes camoflagues the cells that do have answers > 0. (I cant conditional format with color coding because the spreadsheet will be printed on colored paper.)

Thanks in advance to anyone who is able to assist!
