kurmamıştım ama onunla olabiliyor diye hatırlıyorum bi araştır istersen...
Bu aşagıdaki class ile büyük sayıları toplayıp çıkarabilirsin, belki az da olsa işini görür...

belki aralarında vardır çarpma/bölme işlemini yapan vardır.
big number calculations php
kolay gelsin...
çarpma / bölme olayını aşarsan eğer , kodları paylaşırsan sevinirim. ....
