# PEMDAS unexpected result

I have entered the following expression in sagemath 9.0 on Linux

(3^2 * 4^2)-(8^2 - 3^2)//(6^2-9*8)

and sage gives 146 as the result. Nevertheless, I solved on paper and I get 145.

So my question is Am i doing something wrong with PEMDAS on sagemath?

Thank you in advance.
