下面1句可调成2句（即交换but与although位置）这样吗？

下面1句可调成2句（即交换but与although位置）这样吗？

I tried doing the accounts, but although I knew some maths I found it very difficult.
我试着算这些账，但尽管我懂点数学，仍感到很困难。此句将 but 与 although 用在一起，但此句也没有错误。该句从总体来看，它是一个以并列连词 but 连接的并列句，而在该并列句的后面一句又是一个包含让步状语从句 although I knew some maths的复合句，这种句型就是所谓的并列复合句。此句也可改写为 I tried doing the accounts, but I found it very difficult although I knew some maths.追问然而可以否
