anywhere you use a LEFT() function, wrap a cast around it.

select cast(left() as int)

it should look like this:

Select
      CAST((
       Select
            Left(((Sum([Size]) * 0.0009765625) * 0.0009765625), 3) as 'Size combined in MB'
       FROM
            SharePoint_WSS_Content.dbo.AllDocs
       Where
            DirName not like '%/masterpage%'
            and DirName not like '%Reporting Templates%'
            and DirName not like '%/_themes%'
            and DirName not like '%_catalogs%'
            and DirName not like '%Style Library%'
            and DirName not like '%/forms%'
            and DirName not like '%_cts%'
            and DirName not like '%FormServerTemplates%'
            and DirName not like '%IWConvertedForms%'
            and DirName not like '%/_t%'
            and DirName not like '%/_w%'
            and leafname not like '%.aspx'
            and leafname not like '%.xsl'
            and leafname not like '%.000'
            and Leafname <> 'Thumbs.db'
            and leafname like '%.%'
            and TimeCreated > convert(char(10), getdate(), 1)
            and Len(DeleteTransactionId) = 0
      ) AS INT)
      - CAST((
         Select
            Left(((Sum([Size]) * 0.0009765625) * 0.0009765625), 3) as 'Size combined in MB'

it has a period....you'll have to wrap a replace around it like I did the cast

Select
      CAST(
            REPLACE(
            (
       Select
            Left(((Sum([Size]) * 0.0009765625) * 0.0009765625), 3) as 'Size combined in MB'
       FROM
            SharePoint_WSS_Content.dbo.AllDocs

            DirName not like '%/masterpage%'
            and DirName not like '%Reporting Templates%'
            and DirName not like '%/_themes%'
            and DirName not like '%_catalogs%'
            and DirName not like '%Style Library%'

            and DirName not like '%_cts%'
            and DirName not like '%FormServerTemplates%'
            and DirName not like '%IWConvertedForms%'
            and DirName not like '%/_t%'

            and TimeCreated > convert(char(10), getdate(), 1)
            and Len(DeleteTransactionId) = 0
      ), '.', '') AS INT)
      - CAST(
            REPLACE(
            (
         Select
            Left(((Sum([Size]) * 0.0009765625) * 0.0009765625), 3) as 'Size combined in MB'
