Could you please check by homework if I got it right??

Given
[tex]-35+(30+5)[/tex]To find the sum.
Now,
It is given that,
[tex]-35+(30+5)[/tex]Then,
[tex]-35+(30+5)=-35+35[/tex]Since -a+a=0, if a is any number.
Then,
[tex]\begin{gathered} -35+(30+5)=-35+35 \\ =0 \end{gathered}[/tex]Hence, the answer is 0.
