Answer :
0
as using bedmas you must multiply before you add and subtract so once you multiply 50 by 1 you get 50 and then 60 times 0 is zero so 50-60 is equal to -10 plus 10 you get 0
[tex]Use\ PEMDAS\\0+\underbrace{50\times1}_{50}-60\underbrace{-60\times0}_{0}+10=0+50-60-0+10\\\\=50-60+10=-10+10=\boxed{0}[/tex]
