Math_98 and Math_65 are two-hunk bugs

[OrochiKyito]

Hi, author! first, thanks for you wonderful work CURE.

I found in your patch, Math_65 and Math_98 are fixed by one-line change. However, according to http://program-repair.org/defects4j-dissection/#!/, they are both two-hunk bugs. So I wonder the two patches are actually plausible.
